Explain the principle of luminous powder, the principle of luminous powder

Luminous powder (commonly known as luminescent powder), after being exposed to natural light, daylight, ultraviolet light, etc., stores the light energy, and after slowly stopping the light, it is slowly released in a fluorescent manner, so at night or in the dark, still Can see the light, lasting for hours to ten hours. The radioactive night light powder is a radioactive substance mixed in the phosphor, and the fluorescent light emitted by the radioactive material is used to excite the phosphor to emit light. Such luminous powder has a long light-emitting time, but the application range of toxic and harmful and environmental pollution is small. Pigments (light powder, phosphor, light storage powder, light storage powder, luminous powder, luminescent pigment) can be used as an additive or pigment. Evenly distributed in various transparent or translucent media, such as paint, oil black, plastic, rubber-printed glass, ceramics, chemical fiber, to achieve the self-illumination function of the medium, showing a good low-level lighting indication and decorative beautification effect.

characteristic:

1. Rare earth luminescent powder does not contain any radioactive substances, non-toxic, harmless, non-combustible, free of phosphorus, lead and other harmful elements or chemicals. It is safe for human body and passed the test of the national authoritative testing department.

2. Has stable physical and chemical properties.

3. The service life can reach more than 20 years.

4, tiny particles, easy to mix with a variety of transparent media raw materials.

Application areas:

The luminescent product made of luminescent pigment rare earth luminescent powder has unique functions, wide application fields, large market range, great commercial value, and good social and economic effects.
