【摘要】 本文采用溶胶－凝胶法在玻璃基片上涂敷，制备了掺杂ＣｄＳ微晶的ＴｉＯ_２复合薄膜。采用ＸＲＤ、ＴＥＭ研究了薄膜的物相及其结构特征；Ｕｖ－ｖｉｓ－ｎｉｒ谱研究了薄膜的光吸收特性；光生电流谱研究了薄膜的光电转换效率。结论表明：ＣｄＳ的掺入有利于薄膜对可见光吸收的增强，从而提高其采光效率及光电转换效率。更多还原

【Abstract】 CdS-doped TiO₂ film on common glass has been developed by dip-coating. The phase and structure of the film have been studied with XRD and TEM; The absorbency of the film has been researched with Uv-vis-nir spectroscopy; The light-converting efficiency has been researched with photocurrent measurements. The results indicate the absorbency to solar light and light-converting efficiency is improved when CdS nanocrystals is doped into TiO₂ film.更多还原
