Combustion Synthesis and Photoluminescence of Ca_3(VO_4)_2∶Eu~(3+)

Ca3(VO4)2∶Eu3+was prepared by modified combustion synthesis using urea as the fuel and metal nitrates as oxidants. These phosphors were characterized by XRD,SEM, and photoluminescence under 300 nm excitation. The SEM image shows that the size of the phosphor particles is uniform. The main emission peak of Ca3(VO4)2∶Eu3+ was 614.0 nm, The feasibility of employing these phosphors in PDP and lamps was described. It is expected that Ca3(VO4)2∶Eu3+ would be promising red emitting phosphors candidates for PDP .
