Synthesis and Luminescent Properties of Micro – Nanometer Ca0.69Sr0.23(PxMoy)O4:0.05Eu3+ by Co Precipitation – Melted-Salt Method
High luminescent intensity micro – nanometer Ca0.69Sr0.23(PxMoy)O4:0.05Eu3+ phosphor were synthesized by an innovative co precipitation-melted-salt (CPMS) method, Using Eu2O3, Ca(OH)2, SrCO3, HNO3, (NH4)6Mo7O244H2O, (NH4)2HPO4 and inorganic flux as raw materials, room temperature co precipitation and Melted-salt-calcination at 800°C. The results show that the Ca0.69Sr0.23(PxMoy)O4:0.05Eu3+ emits strong 615 nm red light ( exited by 285 nm UV), the luminescent intensity of phosphor is the highest when x / y = 1. The size of the dispersed phosphor is about 1.0 μm. The phosphors have great potential applied as photon conversion materials in Si-solar photovoltaic system and devices.
