【Abstract】 The excitation spectra of tungstate and molybdate red emitting phosphors excitated by Eu³⁺ is similar to the emitting spectra of ultraviolet and blue light emitting diode（LED）.This phosphor can be effectively excited by ultraviolet （394nm） and blue（464nm） light,and exhibits a satisfactory red performance,nicely fitting with the widely applied ultraviolet or blue LED chips.It is very important for the development of white LED,and become the emphasis of research to red emitting phosphor used on white LED.更多还原
