WOLSTENHOLME printing special luminous | RE luminous | afterglow luminous purple luminous [RE] RE afterglow phosphors (also known as "luminous") is a capable of receiving natural light (sunlight) and a variety of light sources (fluorescent, incandescent energy, etc.), the optical storage up, and then release the new optical storage material visible in a fairly long period of time, usually sustained glow in the dark for 8-10 hours, so called rare earth long afterglow phosphor. The main emission wavelength at 520nm nearby emit green, changing components will be able to emit blue-green light. Compared with the traditional long-lasting material zinc sulfide system, rare earth materials with high brightness long afterglow, afterglow long time, resistance to radiation, long life of long-term exposure to sunlight does not fail and so on. Also a non-radioactive hazardous afterglow phosphor material. Aroused widespread interest since the 1980s to make, has been widely used in advertising, road signs, indoor indicators, luminous watch, boats, lighthouse. Gold Point luminous rich reserves of rare earth in China as raw material, through a special process synthesis, brightness afterglow, afterglow long time, wide application, non-toxic, harmless, non-radioactive and other advantages. [] Luminous luminous pigments emitting luminescent pigment is a powdery light storing luminous organic material, a variety of visible light by absorbing a light emitting function, especially shortwave visible light below 450 nm has a strong absorptive capacity, and can be reused many times. The product does not contain a radioactive element, can be used as an additive in homogeneous distribution such as: coatings, inks, paints, plastics, printing paste, ceramic, glass, fibers, and various transparent media type, light emission functionality of the medium. [How to make] Gold Point luminous luminous luminous absorb all kinds of ordinary visible light for 10-20 minutes, then for a long time self-luminous. Luminous colors blue, green and yellow-green orange purple red white blue green sky blue orange (average particle size 20-40um)
