| 摘 要： | 研究了温度对来自镶嵌在BaO薄膜中的纳米银粒子的光电发射的影响。在不同温度下计算和讨论了其光电发射谱（入射波长在0.2~0.8 μm）。光电发射谱中温度越高，光电发射峰越大。同时发现镶嵌在BaO薄膜中银纳米的临界尺寸小于3.8 nm。

| Abstract: | The Dependence of the spectral distribution of photoemission from silver nano-particles embedded in BaO semiconductor thin film on temperature are predicted and investigated theoretically. At high temperature the photoemission response curves to wavelengths from 0. 2 to 0. 8 μm are given. It is showed that the higher temperature,the higher photoemission from silver nano-particles embedded in BaO. An explanation is also presented. It is also pointed out that the critical diameters of silver nano-particles between discrete electron eigenstates (quantum sizes region) and quasicontunuous energy bands for energy band of silver ultra-fine particles in the BaO are less than 3. 8 nm |
