摘要：

The effects of charge compensation on the luminescence behavior of a red-emitting phosphor, Ca3Sr3(VO4)(4):Eu3+, were investigated. It has been observed that charge compensated by monovalent ions, especially Na+, shows greatly enhanced red emission under ultraviolet excitation. It is found that Na2CO3 addition acts as a fluxing agent and plays a role in charge compensation, which clearly improves the emission intensity of Eu3+-activated Ca3Sr3(VO4)(4). Enhanced emission intensity of the corresponding charge compensated phosphors under ultraviolet radiation may find application in the production of red phosphors for white light-emitting diodes.
