Can also be used together with a variety of translucent plastic pressed into a variety of symbols, components, supplies, the most common is the night view function on the switch. These light-emitting components after light exposure at night to get up at night to go home when it's still continue to light,glow in the dark pigments so that people identifiable switch position, bring convenience to work and life. Transportation Application: ultrafine particles incorporated into the luminous material in textiles, to make the color more vivid, luminous textiles kids wear can reduce traffic accidents, traffic or road cleaners would often wear such clothes, so that the vehicle had lived easy identification. Ground traffic cones, ground or isolation barrier luminous guide wire is also used this material.

glow in the dark material characteristics

In the glow in the dark material in the field, the study of organic materials increasing people's attention. Because many types of organic compounds,glow pigments adjustable, good, rich colors, high color purity, molecular design is relatively flexible. Depending on the molecular structure of the organic light emitting material can be divided into: (1) an organic small molecule light emitting material; (2) an organic polymer light-emitting material;glow in the dark sand (3) an organic luminescent material complexes. These luminescent material emitting mechanism in terms of physical and chemical properties, or in the application on has its own characteristics.

the French Academy of Sciences glow in the dark pebbles

By the end of 1895, the German physicist Roentgen discovered a highly penetrating radiation, due to the nature of it does not understand, so named X-rays. After the discovery of X-ray after the news spread, the whole world sensation. 

January 20, 1896, the French Academy of Sciences held a regular meeting on Monday, the famous mathematician, physicist Poincare introduced Roentgen's discovery, also exhibited an X-ray photograph. His report aroused great glow in the dark rock‍ interest of the participants. After the meeting, the French physicist Burke Harrell rushed back to his lab. He and his father have long been studying the fluorescence phenomenon, they found that some of the material in the sunlight emits fluorescence. This discovery led to many applications today: fluorescent lamp called, because it's inside of the tube is coated with phosphor; are coated with a phosphor dot on the 12 hour luminous watch, after daylight illumination after their night after listening to Poincare able luminous ...... reports Burke Harrell feel the need to verify whether the fluorescent substance can emit X-rays. 

In early February, Burke Harrell began his experiments. He took a bottle of fluorescent substance - a yellow-green potassium uranyl sulfate, a substance in the sunlight will fluoresce, Burke Harrell wanted to know whether they will also emit X-rays. He modeled Roentgen X-ray inspection method, the photographic film with a black wrap tightly, then pour a spoonful of phosphor on the parcel, and then get the sun go down while drying. glow in the dark pigments‍ Burke Harrell then pour the phosphor to go back to the bottle, then took the bag with a black wrap film into the camera darkroom, after flushing has been found photographic negatives, and spoon on top of it is that the phosphor geometry shadow. Burke Harrell knew that the sun and fluorescent light can not penetrate the black paper to make photographic film. Now the film is sensitive, and this shows the phosphor after the sun can really emit X-rays, X-rays can penetrate because only black paper to make photographic film. So Burke Harrell at a regular meeting of the Academy of Sciences on February 24, briefly reported the discovery. 

next regular meeting glow in the dark stones

In order to make the next regular meeting of the official report, Burke Harrell ready to do an experiment. But bad weather, rainy days in a row starting from February 26. He had to be disappointed with the phosphor and black glow in the dark powder‍ wrap was sternly put together photographic negatives desk drawer, waiting for fine weather. When the drawer shut him shoving a key pressed on black paper bag and placed the bottle on the edge of a fluorescent substance.

March 1 weather cleared, Burke Harrell ready to proceed with a new experiment. Two specially drawn carefully, he took a look at the film before the experiment to see whether the light leakage. Results of spot checks to make Burke Harrell shocked: Two negatives are exposed, on which there is a shadow of that key! How is this going? After the film is wrapped with black in a drawer, but also the continuous rainy days, there is less sunlight shine, bottle of fluorescence emitted fluorescent substance is not, why would a photosensitive film it? 

After careful analysis, Burke Harrell guess, probably double uranium oxide and potassium sulfate itself emits an invisible rays, these rays are like X-rays, as can penetrate black paper to make photographic film. At a regular meeting on March 2 Academy, glow in the dark pigments‍ Burke Harrell excited to announce this new discovery, and his original statement is unreasonable inferences. In fact, in the sunlight dioxygen potassium sulfate uranium fluorescence emitted does not contain the X-rays. Burke Harrell initial experiments done under the sun, radioactive rays actually make the film a sense of light, but he mistakenly thought it was an X-ray Bale. 

Burke Harrell has designed glow in the dark material

After the March 2 meeting, Burke Harrell has designed and made a series of experiments. He was such a uranium salt crystals heating, refrigeration, and research into powder, dissolved in acid, such as for physical or chemical processing on, he found that as long as the compound contains uranium, there is this magical penetrating radiation. Burke Harrell also experimenting with pure uranium metal, found double the oxygen it produces glow in the dark ‍ radioactive than uranium and potassium sulphate strong three, four times. He put this radiation is called "uranium rays." At a regular meeting of the Academy of Sciences on May 18, Burke Harrell announced uranium or uranium salts spontaneously emitted radiation (uranium rays). This is a new, self-generated by the atomic beam, the intensity of this radiation is not affected because of the heating, cooling, pulverizing and dissolving on physical or chemical changes occur, in other words, these rays are very "way "No matter what kind of impact it is applied to the outside world, it consistently emit rays. This major discovery Burke Harrell and Roentgen discovered X-rays together, sounded the world welcomed the atomic era bell. To this end, Burke Harrell won the Nobel Prize in Physics for the year 1903. 

Afterwards, some people think that Burke Becquerel discovered radioactivity by accident. How come we look at this issue? Of course, that coincided with the rainy days, this is accidental factors. However, Burke Harrell experiment very carefully, Pro also checks before doing the film, it is not a matter of chance, but should be attributed to his rigorous scientific attitude. If he is only an experiment, or do not spot the film, it is glow in the dark pigments‍ impossible to succeed. In fact, with Burke Harrell roughly the same period, the scientists also discovered another double uranium oxide film with potassium sulfate together are sensitive. However, he thought it had nothing to study this phenomenon took place easily passed. 

The famous French scientist Pasteur said a maxim: 

"In the field of observation, the opportunities for those who prefer only the prepared mind." 

Burke Harrell is a "prepared mind," the eminent scientist, so when you look closely at the things around, there is a significant discovery.‍
