采用溶胶凝胶法制备了Y4Zr3O12∶Eu3+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Eu3+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Eu3+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。

Y4Zr3O12∶Eu3+ 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 Eu3+ 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 Eu3+ mole fraction are 1 400 ℃ and 18%, respectively. The mechanism of concentration quenching is attributed to the electric dipole-dipole interaction.
