| 摘 要： | 采用燃烧法制备得到CeO2∶Er3+纳米晶粉末.用X射线衍射仪(XRD)、高分辨透射电子显微镜(HRTEM)和荧光分光光度计等对CeO2∶Er3+纳米晶的结构、形貌和上转换发光特性进行了研究.结果表明:所得到的纳米晶粒度均匀、结晶完好,属于立方萤石结构.上转换发光光谱的研究表明:在980nm红外光激发下,可以发现上转换荧光,分别来自于Er3+离子的2H11/2,4S3/2→4 I15/2和4 F9/2→4I15/2跃迁.

| Abstract: | CeO2:Er3+ has been successfully fabricated by combustion synthesis.X-ray diffraction(XRD),high-resolution transmission electron microscopy(HRTEM),fluorescence spectrometer were used to characterize the structure,surface morphology and upconversion luminescence properties of CeO2:Er3+.The prepared samples had a cubic fluorite structure.The results showed that the upconversion emission can be attributed to the 2H11/2,4S3/2→4I15/2 and 4F9/2→4I15/2 transitions of Er3+,respectively. |
