Glow in the dark materials type

Glow in the dark materials luminescence is varied, the main types are: photoluminescence,Glow in the dark pebbles cathodoluminescence, electroluminescence, thermoluminescence, optically stimulated luminescence, radiation luminescence.glow in the dark materials and different from incandescent. Since the material but cold objects chemical reaction energy,Photoluminescent Aluminum Sheet subatomic movement or stress caused by intracrystalline radiation.
Glow in the dark materials in addition to the heat radiating material is in the form of light emitted from the excess energy, the emission process has certain duration.
Glow in the dark materials can form a powder, crystal, or amorphous thin films, such as the use of, the main component is a compound semiconductor materials and rare earth metals, a very close relationship with the non-ferrous metals.

4 . The best use of its long-lasting luminous scope and conditions of use, please refer to the specific luminous manual or technical advice.

Mainly because there is no industry standard yet luminous

Mainly because there is no industry standard yet luminous , but not our traditional understanding of the consumer in the price of the product , there must be high relative good performance, especially crafts and toy industry , less demanding on the luminescence time for body color and glow in the dark dye rate is higher demands
Problem absorbance response time for the application of crafts and toy industry is particularly important , but the length of time has not emitting very important, signs and other directions industries emitting time is important , so I hope that when customers choose luminous , where to buy glow powder choice the company's products for their luminous , luminous willing to give you a broader application of the product .

Brightness light-emitting phosphor coating

As the coating thickness increases, the coating also increases the emission brightness , but when the coating thickness reaches a certain value, the coating rate of increase brightness becomes smaller, because the light intensity is contained within the light emitting unit area determines the number of powder , as the coating thickness increases , glow pigment powders includes a number of phosphor increases. However, when the thickness reaches a certain value, the force of the coating covering the bottom of the glow powder suppliers on the light emission luminance contribution coating is reduced, so as to increase the coating thickness increases the brightness of the luminous paint is no longer apparent.

Luminescent material particle size on coating application

Luminescent material particle size on coating application and the luminous intensity has a great influence . If the luminous powder particle size is large, the paint easy precipitation , distributed unevenly affect workability , glow powder suppliers ; if the particle size is too small luminous powder , luminous nature may be destroyed, afterglow time is not long lasting. However, coating processing performance, the luminous powder particle size finer the better , preferably greater than 360 mesh . Luminous powder dosage on the coating properties also have a great impact , luminous powder with less, its total luminous intensity is weak , with the increasing amount of luminous powder , coating significantly increased brightness , but the luminous glowing stone pebbles a certain amount , the then light emission luminance of stable coating . In addition, the luminous powder expensive, its excessive use , will increase the cost of paint . Based on the above considerations, luminous powder dosage of 10% to 20 % is appropriate.

luminous pigment molecules

Rare earth doped alkaline earth aluminates attenuation mechanism exponential decay with temperature , the lower the temperature , the weaker intensity , temperature, light intensity increases rapidly , the decay time is much shorter.
When the coating is lighting conditions , the part of the light is reflected , another portion of the light into the coating interior. Into the glow gravels emitting pigments are partially absorbed by the pigment in the light-emitting molecules are excited , when these molecules will return to the ground state by radiation in the form luminescence . Therefore, the luminous paint luminous paint luminous performance depends . Rare earth doped glow pigment powders aluminate photoluminescent process can be divided into three main stages: light absorption , energy transfer , the emission of light . Absorption and emission of light occurs in the transition between energy levels , have been excited state . Excited state of motion is the energy transfer process .

The rate of excited state level

So long afterglow time depends on the number of electrons in the trap level and the rate of return excited level , afterglow trap level depends on the intensity of the electron in the unit time to return excited level rate.
This luminous paint luminous paint photoluminescent pigment is dominated by the afterglow luminescent properties of the decision. Rare earth doped alkaline earth aluminate luminous emission time is largely determined by the attenuation characteristics and trap effect decisions. Rare earth doped alkaline earth aluminates attenuation photoluminescent films decay with temperature , the lower the temperature , the weaker intensity , temperature, light intensity increases rapidly , the decay time is much shorter.

luminous paint afterglow luminescent properties

The electron trap level quantity, the long afterglow time ; absorb more energy , the electron is excited to overcome the trap level and energy gap between the energy levels (ET), and thus produce sustained luminescence . Photoluminescent pigment energy continues to increase it will make the afterglow time extension , if enough energy to the electron trap level all the time to return excited state level , is not conducive to the extension of time afterglow ; contrary, absorb very little energy , less so that the electron trap levels returned excited state level , but also long-lasting phenomenon was not observed . So long afterglow time depends on Phosphorescent Ceramic electrons in the trap level and the rate of return excited level , afterglow trap level depends on the intensity of the electron in the unit time to return excited level rate.

Fluorescence stick

Fluorescence stick, outer packaged in polyethylene (plastic), built a glass tube sandwich, sandwich liquid inside and outside respectively peroxide and esters, by bending, hitting, kneading, glow in the dark dye and the glass breakage, causing two compounds reaction resulting in luminescence fluorescent dye.
The principle of the luminescence is that the reaction of peroxide and esters is the reaction of the fluorescence, and the energy transmitted to the fluorescent dyes, and then the fluorescence is emitted by the dyes.. The common market of the fluorescence stick usually placed a glass tube sandwich, masterbatch production sandwich and isolated peroxide and esters, after kneading, two compounds reaction makes fluorescent dye luminescence.

fluorescent pigments component structural features

fluorescent pigments are compounds having a specific structure, its structural features are the following three points:
(1), the molecule contains a fluorescing group, such as carbonyl, nitrogen nitrogen double bond, carbon and nitrogen double bond.
(2), containing molecules to help color group. Auxochrome make fluorescence spectral redshifts and increase efficiency, such as primary amine, secondary amine, a hydroxyl group, an ether bond, an amide group.
(3), comprising a rigid planar structure of the molecule of the conjugated π bond. Conjugated molecular systems within the larger plane of stronger fluorescence intensity higher. Some can improve the conjugation of factors that can improve the fluorescence efficiency,photoluminescent pigments and fluorescence wavelength shift to longer wavelengths.

Pigment classified according to chemical composition

fluorescent pigments free now no generally accepted method, the reason is a wide variety of pigments, chemical composition very different purpose is multifaceted, and therefore classified according to which method is not ideal.
More common classification is based on the chemical composition of the pigment will be divided into inorganic and organic pigments. From a performance perspective, inorganic pigments Light, heat resistance, hiding power, but not quite complete chromatography, low tinting strength, bright shade of difference, the larger part of the metal and oxide toxicity. Organic fluorescent pigments manufacturer diverse structure, complete chromatography, bright shade of pure, strong coloring, but the light resistance, weather resistance and poor chemical stability, more expensive.

Due to the high temperature plastic molding process , so should not break down color pigment in molding the heating temperature conditions. General inorganic pigments good heat resistance , poor heat resistance of organic pigments and dyes , this should be taken seriously enough variety in the choice of pigment .

( 2 ) dispersion of the pigment should be a good coloring power . When pigment dispersed unevenly , it will affect the appearance of the performance of products ; pigment tinting strength is poor, will increase the amount of pigment material costs increased. The same pigment dispersion in various resins and color strength are photoluminescent pigment suppliers, so pay attention when choosing this pigment .
The toner particle size and dispersibility of the relationship , the smaller toner particle size , the better the dispersibility , the coloring power is strong.
( 3 ) should be aware of other pigment properties, such as for use in food , children's toys aspects of plastic products, the requirements should be non-toxic pigment ; for electrical aspects of plastic products, electrical insulation should choose good pigment ; plastic products for outdoor areas , should choose a good resistance to weathering properties of pigment and so on.

Luminous powder used in ceramics

In the light emitting luminous ceramic glaze used for high production , light emission pattern can be made according to need , the surface of the article can be completely prepared luminescent . If the glaze settlement, may add 2 a 4% bentonite to increase the Photoluminescent Tumbled Gravel  When the entire surface of the light emitting ◇ The product produced , can be spray glaze or enamel pouring process , the need to add about 2% of kaolin and a small amount of glaze cmc other additives to increase the fluidity of the glaze slurry and suspension .glow in the dark dyes  is applied to obtain a white glazed biscuit best results ; if applied to the red body , the bottom layer of white enamel should be applied . Luminous glazes temperature should be lower than 1100 ℃ for good, above this temperature should be used in order to obtain better results fast firing , in order to obtain a more smooth glaze , the glaze in the light-emitting layer above and then applying a thin transparent glaze.

colorless transparent crystal

Pure colorless transparent crystal quartz variants. Chemical composition containing Si-46.7%, O-53.3%. Due to the presence of different physical or mechanical mixing and showed mixed colors. Purple and green is made of iron (Fe2 +) ion-induced color , purple also be photoluminescent sheet caused due to other color from the color center color . In the crystal containing sand-like , fragmented goethite , hematite, rutile , magnetite , garnet, chlorite inclusions ; hair crystal containing visible in the hair -like needle- like mineral inclusions formation. Manganese and iron are glow pigments ; iron by ( golden yellow or lemon ) called citrine ; manganese and titanium were pink rose quartz who said ; smoked who said smoky quartz ; Brown who said citrine ; black transparent who called smoky quartz ; pale green are known as chalcedony .

Epica phosphor is dissolved therein. B. can be used in oil and water-based paints and inks are . A transparent neutral or weakly basic resin (pH 5-7 most suitable quality ) should be used.

Photoluminescent Pigment

A new type of environmentally friendly photoluminescent pigment

Dy is a new type of environmentally friendly photoluminescent pigment , has attracted wide attention from researchers . Currently, the new luminescent pigments glow in the dark powder  explore some novel methods for preparing the luminescent pigments.
High temperature solid-phase method is the preparation of Eu2 + activated strontium aluminate luminescent materials and traditional method of application of the first maximum . The law mainly Al2O3, SrCO3, Eu2O3, Dy2O3 as raw material , adding a certain amount of flux ( such as boric acid ) , Photoluminescent Tumbled    Gravel, generally the first high temperature (1350 ℃ or so ) calcined , and then restored at a slightly lower temperature that Eu3 + becomes Eu2 +, reducing atmosphere can be 2% H2 +98% N2 to create , we can use a confined space to place active carbon . Finally, after cooling , fine grinding and sieving to obtain the product . This method is very obvious advantages of simple process , microcrystalline crystals of good quality, suitable for industrial production .
