摘 要: 以1,3-丙二胺为结构诱导剂,采用溶剂热法合成了有机-无机杂合的[C3H12N2]0.5[Y3F10]:Yb/Er,采用X射线衍射谱(X-ray diffraction,XRD)、热重分析(thermogravimetric analysis-differential scanning calorimentry,TG-DSC)、扫描电子显微镜(scanning electron microscope,SEM)和电子能谱(energy dispersive spectrometer,EDS)对其结构、形貌和化学组成进行表征。研究表明,通过溶剂热法可以成功合成[C3H12N2]0.5[Y3F10]:Yb/Er,其形貌为呈正八面体的微米级颗粒。在980 nm激光激发下,对其上转换发光性能进行研究。其上转换发射光谱显示其具有较强的上转换发光性能,且发出的绿光要强于红光。
关 键 词: 无机非金属材料; 稀土氟化物;上转换发光;有机-无机杂合物

Abstract: In this paper, [C3H12N2]0.5[Y3F10]:Yb/Er has been successfully synthnsized by solvothermal, using 1,3-propanediamine as structure-direct agent. The samples were characterized by powder X-ray diffraction (XRD), thermogravimetric analysis/differential scanning calorimentry (TG-DSC), scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). It was found that the sample had octahedral morphology with microsize, and performed upconversion fluorescence. The upconversion luminescence was investigated under 980 nm laser excitation, which mainly contains green emission, and red emissions. And the intensity of the green emissions was stronger than that of red emissions.
Key words: inorganic nonmetallic materials; rare earth fluoride; upconversion luminescence; organic-inorganic hybrid compounds
