Luminous powder principle

After being exposed to natural light, daylight, ultraviolet light, etc., the luminous powder stores the light energy, and after slowly stopping the light, it is slowly released in a fluorescent manner, so that the light can still be seen at night or in the dark. It lasts 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.

Looking for luminous powder, the first choice of prosperous effect pigments, more professional service, more assured quality.
