水热法合成LuVO4∶Eu3+红色荧光粉及其光谱性能研究
Hydrothermal Synthesis and Luminescence Properties of Eu3+-activated LuVO4 Red Phosphors
摘要
Abstract
LuVO4∶ Eu3+ nano-(or submicron-) phosphors have been prepared by hydrothermal method without (or with) further heat treatment.The properties of the resulting phosphors are characterized by X-ray diffraction,scanning electron microscope,photoluminescence spectra and decay curve.The excitation spectra of LuVO4∶ Eu3 + phosphors are mainly attributed to Eu→O chargetransfer band at about 275 nm as well as some sharp lines of Eu3 + f-f transitions in near-UV and visible regions with two strong peaks at 395 and 466 nm,respectively.Under the 275 nm excitation,intense red emission peak at 619 nm corresponding to 5D0→7F2 transition of Eu3+ is observed for LuVO4∶ 8% Eu3+ phosphors as the optimal doping mole fraction.The luminescence properties suggest that LuVO4∶ Eu3+ phosphor may be applied as a potential red phosphor candidate for lighting and displays.关键词
