中文摘要：

利用溶胶．凝胶法制备了纳米金属颗粒分散氧化物Ag／NiO复合薄膜，用X射线荧光光谱、X射线衍射分析、透射电子显微镜、紫外可见分光光度计表征了薄膜的成分、相结构、微结构以及光吸收特性。X射线衍射分析结果表明存在NiO相和单质Ag相。光吸收谱研究表明，Ag／NiO薄膜在410nm波长附近有明显的表面等离子共振吸收峰，随着Ag含量的增加，吸收峰变窄，蓝移，强度增加。当Ag含量接近41％（质量分数）时，Ag／NiO薄膜在414nm波长附近表现的吸收峰呈现最大的吸收强度；当Ag分散颗粒的含量超过41％（质量分数）后，吸收峰的强度开始下降。随着保温时间的延长，薄膜的光学吸收峰的强度增强，并且吸收峰峰位向波长短的方向移动。

英文摘要：

Ag nanoparticles dispersed nickel oxides composite films were prepared by sol-gel method. The phase structure, composition, microstructure and optical absorption properties were characterized by X-ray diffraction analysis, X-ray fluorescence spectrum, transmission electrons microscopy and U-vis spectrometer. The XRD analysis indicated that both NiO and metal Ag phases existed. The optical absorption spectrum indicated that the Ag/NiO films had obvious surface plasmon resonance peak at the wavelength of around 414 nm. With Ag content increasing, the absorption peaks became narrow and blue-shifted, and the intensity of the peak increased as well. When Ag content was near to 41wt%, the absorption peaks showed the largest intensity at the wavelength of about 414 nm, and then the intensity of absorption peak decreased. Prolonging the heat duration led to red-shifting of the optical absorption peaks and to increasing the peaks intensity.
