GdAlO_3:RE powder was prepared by nitric-citric process. Luminescent intensity of (GdAlO_3:) Eu decreased when it was co-doped with Pr, and GdAlO_3:Tb co-doped with Ce showed the same phenomenon. The results from excitation spectra indicated that there are the resonant energy transfer between Eu and Pr, Tb and Ce, by the absorption and emission of lower energy phonon. The resonant energy transfer between different RE species is one of main reasons why luminesent intensity decreasing.

采用柠檬酸盐硝酸盐燃烧法制备GdAlO3:RE荧光粉体.在紫外光激发下(254nm)发现Pr共掺杂对GdAlO3:Eu红色荧光粉体发光有降低作用;Ce共掺杂对GdAlO3:Tb绿色荧光粉体发光有降低作用.激发谱研究表明,共掺杂时分别存在Eu→Pr、Tb→Ce的声子支持的共振能量传递,造成GdAlO3:Eu、GdAlO3:Tb荧光粉体发光强度降低.

采用高温固相法合成了FED用Y2O3∶Eu红色荧光粉,为提高其导电性,采用表面成膜包覆法对其进行了In2O3包膜研究。通过XRD,Zeta电位,SEM及低压光谱分析等检测手段分析了包膜前后Y2O3∶Eu的晶体结构、电位、形貌与发光性能,探索了包膜工艺。结果表明:在Y2O3∶Eu表面包覆3%的In2O3能有效改善荧光粉的发光亮度,这种改善的可能原因是包覆In2O3改善了Y2O3∶Eu晶粒表面的导电性。
