| 摘 要： | 本文报道了用燃烧法制备的纳米（5～100nm）Gd2O3：Eu和Y2O3：Eu荧光粉，对它们的晶体结构和光致发光性质进行了研究．结果表明，纳米Gd2O3：Eu和Y2O3：Eu的光致发光性质与常规的Gd2O3：Eu和Y2O3：Eu的性质有很大的差别，纳米Gd2O3：Eu和Y2O3：Eu表现出很强的介观效应．对实验结果进行了初步的探讨．

| Abstract: | The structure, TEM morphology and photoluminescence(PL) of nanocrystallites Ln2O3;Eu (Ln=Gd, Y) phosphers were studied. Samples were prepared by glycerin(G)-nitrate(N) sollltion combustion synthesis. The particle size of Ln2O3 could be controlled by different ratio of G/N.the influences of mesoscopic effect on PL of Ln2O3: Eu, such as the red shift of the excitation peak,the broading of emission peaks, were discussed. |
