Synthesis and Luminescent Properties of Micro – Nanometer Ca_0.69Sr_0.23(P_xMo_y)O₄:0.05Eu³⁺ by Co Precipitation – Melted-Salt Method

Abstract:

High luminescent intensity micro – nanometer Ca_0.69Sr_0.23(P_xMo_y)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 Ca_0.69Sr_0.23(P_xMo_y)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.
