中文摘要：

通过溶胶-凝胶法,制备了钙钛矿型CaTiO3∶Sm3＋纳米发光材料。采用XRD对样品进行物相表征。通过电致发光和光致发光测试研究了样品中Sm3＋的发光特性,Sm3＋可发出明亮的橙红色光,但样品的EL和PL谱存在一定的差别。通过分析发光测试结果,认为纳米颗粒中存在两种晶体结构SiteⅠ和SiteⅡ,分析了不同结构对电致发光和光致发光的影响,EL主要依赖于SiteⅠ中Sm3＋,PL主要依赖于SiteⅡ中Sm3＋,并通过实验验证了基质结构对Sm3＋发光的影响。

英文摘要：

A sol-gel synthesis method was introduced to incorporate trivalent samarium ions into perovskite CaTiO3 nanoparticles luminescent materials. The resulting materials were characterized by X-ray diffraction （XRD）. The properties of luminescence of Sm^3＋ in the sample were studied by measured electroluminescence and photoluminescence, Sm3＋ can emit salmon pink light brightly. However, the patterns of EL and PL are not the same. After analyzing the test results, we think there are two crystal structures.. Site Ⅰ and Site Ⅱ , and analyzed the influences of different structures on EL and PL, the EL mainly depended on the Sm^3＋ in Site Ⅰ , the PL mainly depended on the Sm^3＋ in Site Ⅱ , and validated the influences of matrixes＇ structures on luminescence of Sm^3＋ with experiments.
