| 摘 要： | 采用溶胶-凝胶法制备得到Y3 和Ho3 掺杂的TiO2薄膜,XRD分析表明薄膜结晶性能良好,具有锐钛矿晶型。薄膜表面AFM分析表明,薄膜的晶粒具有纳米尺寸。采用紫外-可见分光光度计对掺杂和未掺杂的TiO2薄膜进行紫外-可见吸收光谱分析,表明Y3 和Ho3 掺杂的TiO2薄膜在紫外光区吸光度有所提高,同时在可见光区光吸收范围出现了红移,相同掺杂浓度的Y3 和Ho3 掺杂的TiO2薄膜,前者在400~450nm的可见光区具有更高的吸光度。

| Abstract: | TiO2 films doped with Y3 and Ho3 ions were prepared with sol-gel method.X-ray diffraction analysis showed that the films crystallized well with anatase crystalline.AFM analysis showed the films had nanocrystallines.UV-Vis absorption analysis of the films indicated that the films doped with Y3 and Ho3 ions had higher absorbance in UV district,and the films had a red-shift of absorption edge in visible district,the films doped with Y3 ion had higher absorbance than the films doped with Ho3 ion with the same ion concentration. |
