摘　　要：采用表面活性剂(十二烷基苯磺酸钠)辅助的均相沉淀法,将稀土荧光前驱体氧化物复合在具有一维结构的碳纳米管表面,成功制备了具有一维结构的CNTs@Y2O3:Eu3+纳米复合材料。通过SEM、XRD、TEM-EDS、FT-IR、TGA和PL等表征手段分别探究了复合材料的微观形貌结构、热稳定性、结晶度以及荧光性能。研究结果表明,CNTs@Y2O3:Eu3+荧光复合材料在UV激发下显示出强烈的稀土Eu3+特征荧光。同时,在400~1000℃不同煅烧温度范围内,该复合材料荧光强度随之发生明显变化,具有较强的温度敏感特性。CNTs@Y2O3:Eu3+nanocomposites with one-dimensional structure were successfully prepared by homogeneous precipitation method using surfactant sodium dodecylbenzenesulfonate.In order to investigate the microstructure,thermal stability,crystallinity and fluorescence properties,the obtained materials were characterized by SEM,XRD,TEM-EDS,TGA and PL.The results show that CNTs@Y2O3:Eu3+fluorescent composites exhibited strong rare earth Eu3+characteristic fluorescence under UV excitation.Furthermore,the fluorescence intensity of the composite material changed significantly at different calcination temperature ranges of 400~1000℃,showing strong temperature-sensitive characteristics.
