In this work, we present the results of a unique study that aims to detect the degradation of the individual silver nanoparticles peak in the photoluminescence spectra of the Ag/Ag₂O composites synthesized by treating silver thin films manufactured by thermal evaporation method with oxygen plasma afterglow. The analysis of the spectroscopic data yielded an interesting finding that, the individual silver nanoparticles peak degradation observed in the optical absorption spectra has a mirror image in the photoluminescence spectra. In addition, we found that this degradation arises due to the mutual interaction between the individual silver nanoparticles located near the Ag₂O grain shell and the larger silver nanoparticles inside the grain and it related to the silver oxide grain size.

在这项工作中，我们提出了一项独特的研究结果，该研究旨在检测通过用氧等离子体处理热蒸发法制备的银薄膜而合成的Ag / Ag ₂ O复合材料的光致发光光谱中单个银纳米颗粒峰的降解。余辉。光谱数据的分析产生了一个有趣的发现，即在光吸收光谱中观察到的单个银纳米颗粒峰降解在光致发光光谱中具有镜像。此外，我们发现这种降解是由于位于Ag ₂ O晶粒壳附近的单个银纳米颗粒与晶粒内部较大的银纳米颗粒之间的相互作用而引起的，并且与氧化银晶粒尺寸有关。
