Laser fragmentation of Ag₂O micropowder in water has been experimentally explored. Ag₂O nanoparticles (NPs) obtained using this strategy were characterized using optical spectroscopy and transmission electron microscopy (TEM). High-resolution TEM images indicate that laser exposure leads to the partial reduction of Ag₂O to metallic Ag. As a result, some NPs exhibit a core-shell structure with a metallic Ag core or several Ag cores with a common Ag₂O shell. The main mass of the fragmented colloidal solution of Ag₂O was comprised of NPs with a particle size of 40 nm. The mechanism for the partial reduction of Ag₂O to metallic Ag and the possible applications of Ag₂O NPs have been discussed in detail.

已经通过实验探索了水中Ag ₂ O 微粉的激光破碎。使用该策略获得的Ag ₂ O 纳米粒子 (NP) 使用光谱学和透射电子显微镜 (TEM) 进行表征。高分辨率 TEM 图像表明激光曝光导致 Ag ₂ O部分还原为金属 Ag。因此，一些纳米颗粒表现出具有金属 Ag 核或几个具有共同 Ag ₂ O 壳的Ag 核的核壳结构。Ag ₂ O的碎片胶体溶液的主要质量由粒径为 40 nm 的 NPs 组成。对部分还原Ag的机构₂到金属Ag O和Ag的可能的应用₂已详细讨论了 O NP。
