Y2O3:Eu3+,Dy3+纳米荧光粉的 白光发射性能
White Light Emission Performance of Y2O3 : Eu3+,Dy 3+ Nanophosphors
摘要
Abstract
A series of Dy3+ single doped, Eu3+, Dy3+ codoped and Sr2+, Eu3+, Dy3+ codoped Y2 O3 nanophosphors was prepared by high-temperature solid-state sinter method. The crystal structures and morphol-ogies of the samples were analyzed by means of XRD and SEM, and the preparation progress and parameters were optimized. The excitation and emission spectra of rare earth ions doped Y2 O3 phosphors were measured systematically. Under 330 nm excitation, the characteristics of white light emission of Y2 O3 : Eu3+,Dy3+phos-phors were investigated, and the ideal CIE value(0. 32, 0. 33) and color temperature(6100 K) were achieved through adjusting the concentration of europium and dysprosium ions. At the same time, the influence of biva-lent strontium ion on the white emission properties was further discussed. The result showed that the emissions of white light from Y2 O3 : Eu3+,Dy3+ nanophosphors were improved significantly because of strontium dopant.关键词
