Luminescent pigment is a kind of rare earth elements as the main raw material, non-toxic, tasteless, non-radioactive energy saving new materials, optical radiation can be converted into energy stored up in the cold light into the dark state is released. Accept light for about 5 minutes, at night or in the dark color of the sustainable release of a variety of high afterglow luminance, the afterglow time for more than 12 hours. Material performance is very stable, without any capsule treatment, exposure, high humidity, low temperature, strong ultraviolet radiation and other harsh environments, not black not bad, good light-emitting state, the service life of over 30 years in many luminescent pigment field showed a good emergency lighting, logo and decorative landscaping features, can be safely used for clothing, tools, watches, switches, signs, toys, crafts, sporting goods, etc., and the lighting, daily life, industrial equipment, instrumentation , transportation and tourism, marine aviation, fire safety, architectural, military defense, traffic signals, oil mining, marine exploration, advertising signs, business subtitles as well as mobile phones, computers and other fields are widely used. As an additive, uniformly distributed in the paint, ink, paint, plastic, printing paste, ceramic, glass, fiber and other various media, the media to achieve light-emitting function. Currently luminous paint luminous colors company has four kinds: orange yellow green blue red blue and green day
