| 摘 要： | 采用溶胶-凝胶法制备了Eu3+掺杂的钛酸钇晶态发光薄膜。通过X射线衍射(XRD)对薄膜的结构和结晶过程进行了分析,利用荧光分光光度计对薄膜的发光性质开展了测试和研究。XRD结果表明,薄膜包含立方相YxTi1-xO1-0.5x晶粒,该晶粒属立方晶系,Fm3m(225)空间群,晶胞参数a=0.530nm,晶粒尺寸约为17nm。荧光光谱表明,Eu3+掺杂的YxTi1-xO1-0.5x薄膜显示了强的红光发射,其中Eu3+的5D0→7F2超灵敏跃迁为最强一组。紫外氙灯、准分子激光器、汞灯等是这种发光薄膜的有效激发源。

| Abstract: | Eu3+-doped YxTi1-xO1-0.5x crystal film was spin-coated on quartz glass substrates through sol-gel route. The structure and luminescence properties of the resultant film were investigated by X-ray diffraction (XRD) and fluorescence spectrometer, respectively. The results of XRD revealed that the film was made up of YxTi1-xO1-0.5x grains with cubic structure in average size about 17 nm. Typical Eu3+ emission peaks were observed and the strongest emission with red color corresponds to the 5D0→7F2 transition. UV xenon lamps, excimer lasers and mercury lamp are powerful excitation sources for Eu3+ visible fluorescence in the Eu3+-doped YxTi1-xO1-0.5x crystal film. |
