Luminous paint (material)

luminous paint, referring glows in the dark can be a class of materials into self-luminous and phosphorescent two. Since the basic components of which type of luminous material for light-emitting radioactive materials, without absorbing energy from the outside, sustainable light, the radioactivity could cause some harm to humans (depends on the composition), it restricted the application of greater; while STORING luminous material rarely use radioactive material, mainly by the slow release for longer absorb external light, but light enough to reserve a period of time to ensure the light, substantially unrestricted use, but not as self-emission type luminance materials . In recent years, non-toxic and non-radioactive phosphorescent material towards the direction of development, the Department of aluminum, barium, strontium doped rare earth elements obtained by high-temperature sintering luminescent material, is a hundred times the brightness of traditional materials.
