摘要

在三种不同制备方法的样品上测量了Ag2O光电导率的光谱分布。发现光响应取决于样品的制备方式和先前的光暴露。将Ag2O粉末压在纤维素衬底上制备的样品在0.9 μm左右表现出光导峰值，而在氧气气氛中阴极溅射银制备的Ag2O薄层表现出理想的光导体:在可见光下响应平坦，从0.8 μm到更长的波长呈指数下降。并进行了红外光吸收和电导率的测量。结果与氧化银唯一的结构类似物Cu2O的行为进行了比较。

Photoconductivity in Ag2O

The spectral distribution of photoconductivity in Ag2O was measured on samples prepared in three different ways. The photoresponse was found to depend on the mode of preparation of samples and on previous light exposure. Samples prepared by pressing Ag2O powder against a cellulose backing showed a photoconductive peak around 0.9 μm, while thin Ag2O layers prepared by cathodic sputtering of silver in an oxygen atmosphere behaved like the ideal photoconductors: flat response in the visible and exponential decrease from 0.8 μm to longer wavelengths. Some infra-red optical absorption and electrical conductivity measurements were also made. The results are compared to the behaviour of Cu2O, silver oxide's only structural analogue.
