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。

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
3+
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
3+
mole fraction are 1 400℃ and 18%
respectively. The mechanism of concentration quenching is attributed to the electric dipole-dipole interaction.
