摘要：

Bismuth (Bi3+) and phosphorus (P3+) ions doped YVO4:Eu3+ down-conversion materials were prepared by modified sol-gel method to broaden the absorption range of ultraviolet light and enhance the stability of light emission. It is shown that some positions of Yttrium (Y3+) and Vanadium (V5+) ions can be successfully replaced by incorporated Bismuth (Bi3+) and phosphorus (P3+) ions in the YVO4 lattice. As to low Bi3+ doping, the crystal structure is still tetragonal and the position of Y3+ is well substituted by Bi3+. While for low P3+ doping, a homogeneous solid solution is formed between YVO4 and YPO4.Under the excitation of 325 nm, the highest luminescence intensity can be obtained with Bi3+ mole fraction of 0.04 and P5+ mole fraction of 0.10, respectively. In that case, the instensity of YV0.90P0.10O4:0.05Eu3+ can increase up to 1.9 times comparing to YVO4:0.05Eu3+. © 2016, Science Press. All right reserved.
