Abstract
In order to improve the fluorescence intensity of red-emitting phosphor based on alkaline earth sulfide CaS:Eu2+ for white LED (light-emitting diode), many methods were used. When the flux is NH4F, auxiliary activator is Er3+, intensity of phosphor CaS:Eu2+ has the strongest brightness. On the other hand, introduction of Sr could make the maximum excitation band shift to high energy, which make the phosphor match well with blue light GaN-based LED; Mg partly substitute for the alkaline earth Ca could make the intensity of red emitting phosphor increase greatly.
