Y2O3:Eu3+红色荧光粉的制备与发光性能研究
Preparation and Luminescent Properties of Y2O3:Eu3+Red Phosphors
摘要
Abstract
A series of Y2O3:xEu3+red phosphors were prepared via a two-step hydrothermal-annealing method.The influence of Eu3+doping concentration on their crystal structure and luminescent performance was systematically studied.X-ray diffraction(XRD)results indicate that all samples possess a pure cubic Y2O3 phase without impuri-ty phases,and the increased lattice constant confirms the successful incorporation of Eu3+into the Y2O3 lattice.Photoluminescence(PL)spectra show that all samples emit the strongest red light at 611 nm,corresponding to the 5D0→7F2 transition of Eu3+.With the increase of Eu3+doping concentration,the emission intensity first increases and then decreases,reaching the maximum at a molar fraction of 3%,beyond which concentration quenching oc-curs.CIE chromaticity coordinates show that all samples are in the red light region,and the sample with 3%Eu3+has chromaticity coordinates closest to the standard red light(0.64,0.33),showing excellent color purity.关键词
