摘要

采用溶胶凝胶法制备了Y

∶Eu

纳米荧光粉，分别采用XRD、TEM和荧光光谱仪对样品的结构、形貌和发光性能进行了表征，探讨了烧结温度和Eu

掺杂浓度对荧光粉发光性能的影响。结果表明，样品可以被394 nm和467 nm的激发光有效激发。样品的最佳烧结温度和Eu

离子的最佳掺杂摩尔分数分别为1 400℃和18%。浓度猝灭主要归因于电偶极-电偶极相互作用。

Abstract

:Eu

phosphors were synthesized by the sol-gel method. The crystal structure

morphology and luminescence properties were investigated by XRD

TEM and luminescence spectroscopy. The effects of calcination temperature and Eu

concentration on the luminescence properties were also studied. These phosphors can be efficiently excited by 394 and 467 nm. The optimal calcination temperature and optimal Eu

mole fraction are 1 400℃ and 18%

respectively. The mechanism of concentration quenching is attributed to the electric dipole-dipole interaction.
