Photoluminescent properties of Na+, Bi3+ co-doped CaWO4∶Eu3+ phosphor for PDPs

摘要：

　　The photolumlnescent properties of Na,Bi co-doped CaWO4∶Eu3+ phosphor under vacuum ultraviolet (VUV) region excited was investigated.A red emission of CaWO4∶Eu3+ can be observed under 147 nm excitation.It was also found that the photoluminescence intensity of Na doped CaWO4∶Eu3+ would be enhanced than the un-doped phosphors due to Na+ ions would act as a charge compensator and it can restrict the generation of defects in CaWO4∶Eu3+.Additionally,the photoluminescence enhancement of Na+,Bi3+ co-doped CaWO4∶Eu3+ should due to the energy transfer between WO42-,Bi3+ and Eu3+,and Bi3+ ions would act as a medium for the energy transfer,via WO42-→Bi3+→Eu3+.These are expected to be applying in plasma display panels.
