| 摘 要： | 本文报导了用低温等离子体法使ａ－Ｓｉ：Ｈ表面活化，经多步化学反应，将３种菁键合于其表面，并经激光拉曼光谱和Ｘ－光电子能谱表征。测定了键合染料的ａ－Ｓｉ：Ｈ的吸收光谱和光电导。结果表明，光敏染料可使ａ－Ｓｉ：Ｈ敏化，改善其光吸收和光电导。

| Abstract: | Three kinds of cyanine dyes were bonded Chemically to the a-Si:H surface which was activated by low-temperature plasma.Their stuctures were characterized by SERS and XPS.The absorption spectrum and photoconduction of the a-Si:H surface to which the dyes were bonded were also measured.These results showed that the a-Si:H surface were sensitized by dyes,and their photoconductivity was improved to a certain extent. |
