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．
In this paper, the nanostructured (5-100 nm) Gd2O3: Eu and Y2O3: Eu phosphors were prepared by combustion method. Their crystal structures and photoluminescence properties were studied. The results show that the photoluminescence properties of Gd2O3: Eu and Y2O3: Eu are quite different from those of conventional Gd2O3: Eu and Y2O3: Eu. Gd2O3: Eu and Y2O3: Eu show a strong mesoscopic effect . The experimental results of a preliminary discussion.
