The violet or ultraviolet LED chip coated with trichromatic color phosphors or more

decorative gravelCoated with violet or ultraviolet light LED chip or a plurality of colors of trichromatic phosphors, use of the long-wave ultraviolet light emitting chip (370nm-380nm) or violet (380nm -410nm) to excite phosphors to realize white light emission, the method the color is better, but there are also similar problems, and the second method, and the current high conversion efficiency of the red and green phosphors mostly sulfide system, poor stability of such light-emitting phosphors, the light fades large, so development of efficient, low light decay white LED phosphors has become an urgent task.Photoluminescent Rigid Sheets

(YAG) yellow phosphor coating on blue LED chip can be excited by blue light

glow in the dark materialCoated on a blue LED chip can be excited by blue light (YAG) phosphor yellow, blue and yellow phosphor chip emits white light emitted by the complementary formation. The technology is monopolized Japanese Nichia Corporation, and a principle of the shortcomings of this approach is that the phosphor Ce3 + ion emission spectrum does not have a continuous spectrum characteristics, poor color, it is difficult to meet the requirements of low color temperature of lighting, while the luminous efficiency is not high enough, through the development of new phosphors to improve efficiency.Photoluminescent Rigid Sheet

Phosphor hazards:

Photoluminescent Tumbled GravelsSeveral hazards: As phosphors do neon tubes filled process, contain higher amounts of Hg, and therefore the main source of the harm is its dissemination of Hg vapor, authoritative information: mercury vapor 0.04 to 3 mg, it will chronic poisoning people in the February-March; up to 1.2 to 8.5 milligram quantities, can induce acute mercury poisoning, should the amount of 20 mg, will directly lead to death. Once mercury enters the human body, can be quickly dispersed and accumulated to the kidney, chest and other tissues and organs, chronic mercury poisoning can lead to mental disorders, autonomic disorders. Acute symptoms and headache,luminescent sheet fatigue, fever,

sore gums swelling, erosion bleeding, loose teeth and other parts of the skin red spots, pimples, a few kidney damage, individual kidney pain, chest pain, dyspnea, cyanosis acute interstitial pneumonia. Should custody and improper disposal of mercury, but also cause great harm to the environment, which in various forms into the environment, direct contamination of soil, air and water, and then enter the body through the food chain, endangering people's health living, and therefore must not be fluorescent, neon tubes discarded debris everywhere. If the indoor fluorescent tubes cracked, after available iodine of 1 g / cubic meter plus alcohol fumigation or directly with 1 g / cubic meter iodine dispersed on the ground set of 8 to 12 hours, so volatile or sublimation of iodine and mercury in the air to generate hard volatile mercuric iodide, for reducing the concentration of mercury vapor, but also with 5% to 10% of the ferric chloride or 10% bleach rinse contaminated ground

Luminous light-induced energy storage applications

Phosphorescent CeramicPhotoluminescence photoluminescent pigment, is a new class of rare earth aluminate material is based on the traditional rare earth aluminate luminescent material plus additives into high temperature and other external parameters into ions, using a unique formulation and processing technology is refined, appearance is light green and light yellow, light colors are yellow-green, blue-green and green on the short wavelength of 450 nm visible light has a strong absorption capacity, through the absorption of a variety of natural or man-made light, self-luminous function implemented in a dark state, and unlimited recycling, the initial high-luminance light emitting material up to 2-3 hours, gentle curve of the shoulder luminescent afterglow duration up to 10 hours, having very high practical value, radically different from the traditional short-acting luminescent zinc sulfide powder.glow in the dark stone

Photoluminescence properties luminous energy storage

glow in the dark stonesIn real life, people use long luminous light-emitting properties, made weak light source, in the military sector with special uses, put this material is applied to the aviation instruments, watches and clocks, windows, machine various switches signs, door handles, etc., can also be used together with a variety of translucent plastic pressed into a variety of symbols, parts, supplies (such as power switches, sockets, fishing hooks, etc.). These light-emitting components after light irradiation, or unexpected power outages at night, getting up after lightning and so it continues to emit light, so that people around discernible direction, bring convenience to work and life. The ultra-fine particles of luminous materials incorporated in textiles, to make the color more vivid, luminous textile kids wear, can reduce traffic accidentsPhotoluminescent Tumbled Gravel
