【摘要】 金属纳米粒子／介质复合薄膜因其优良的光电特性和超快响应而成为应用背景很强的光电功能薄膜．采用真空沉积的方法制得了ＡｇＢａＯ纳米薄膜，测试到其在室温条件下的红光和蓝紫光波段的光致荧光光谱，认为ＡｇＢａＯ纳米薄膜的荧光发射主要来自于Ａｇ纳米粒子的贡献．与该种材料的紫外可见光吸收谱相比较，分析了ＡｇＢａＯ纳米薄膜材料不同可见光波段的荧光产生机理．更多还原

【Abstract】 Abstract Metallic nanoparticles complex thin film is a new kind of promising photoemissive thin film because of its perfect photoemissive properties and extremely fast optical response. We obtained a light emitting Ag BaO nanometer thin film using vacuum deposition method. Red blue violet range light emission was observed from its photolumine scence(PL). We believe that the origin of PL of Ag BaO thin film is the contribution of the Ag nanoparticles. Compared with its ultraviolet visible absorption spectra, the mechanism of its PL covering different visible light ranges was analyzed.更多还原
