Long time of afterglow luminescent material

Sometimes we go to buy a luminous watch, luminous painting, or other luminous products, glow in the dark dye ， a clear fluorescence at the beginning of the use of these products , but after a period of time, we will find that these products gradually faint fluorescence even finally no light. It's the light duration.

Photo luminescent pigment luminous powder, glow in the dark material is a new type of rare earth aluminate based luminescent materials in the material,which is a traditional type of rare earth aluminate added high temperature additives, and other parameters, external ion, refined formula and unique processing technology and become, the appearance of light green and light yellow, light colors are yellow green, blue green and green, to below 450 nm wavelength shortwave visible light has strong absorption ability, by absorbing all kinds of natural light or artificial light, self luminous function in the dark condition, fluorescent pigments manufacturer and unlimited recycling, the luminescent material starting high brightness can reach 2-5 hours above, the shoulder light curve is gentle, afterglow duration up to 15 hours or more, has very high practical value, completely different from the traditional short effect of zinc sulfide phosphor, light emitting short time.
