The role of colored luminous powder

There are many different types of color luminous powder, and the price is different. The phosphor has the characteristics of good thermal stability, safety and environmental protection. It is suitable for all kinds of white light and can adjust different colors of red, blue, and so on. 1. Phosphors for fluorescent lamps and low-voltage lamps have yttrium-manganese-activated calcium halophosphate phosphors and rare earth trichromatic phosphors. The strontium and manganese-activated calcium halophosphate color luminous powder is prepared by adding a small amount of activator strontium (Sb) and manganese (Mn) to the chloroapatite matrix 3Ca3(PO4)2·Ca(F,Cl)2. The phosphors are usually expressed as: 3Ca3(PO4)2·Ca(F,Cl)2:Sb, Mn. The preparation method of the colored luminous powder can also be different, but the purity requirements of the raw materials are different. Higher.
