Ａｇ－ＢａＯ 薄膜是一种金属纳米粒子埋藏于半导体介质中的薄膜，由于金属纳米粒子与介质间的相互作用，以及纳米粒子的表面效应和量子尺寸效应，使这种薄膜具有独特的光学、电学和光电转换特性．在激光脉冲作用下，它具有多光子光电发射特性，在飞秒超短激光脉冲作用下，它表
Ag-BaO film is a thin film of metal nanoparticles embedded in a semiconductor medium. Due to the interaction between the metal nanoparticles and the medium and the surface effect and quantum size effect of the nanoparticles, the Ag-BaO film has a unique optical and electrical And photoelectric conversion characteristics. Under the action of laser pulse, it has multi-photon photoemission characteristics. Under the action of ultra-short femtosecond laser pulses, it shows
