Spatially controlled growth of oxidize cobalt and silver nanoparticles (NPs) is successfully performed in commercial soda‐lime glass slides using successively field‐assisted solid‐state ion exchange and continuous wave ultraviolet laser exposure. Using different characterizations techniques, it is demonstrated that either CoO or Co₃O₄ NPs are formed, depending on the laser power. The optical properties of the silver NPs are characteristic of metallic silver, which does not suffer from oxidation. The experimental process opens a new way to combine the magnetic properties of Co₃O₄ NPs and the optical properties of Ag NPs.

苏打石灰玻璃中钴和银纳米颗粒的生长

氧化钴和银纳米颗粒（NPs）的空间控制性生长是在商业钠钙玻璃载玻片中成功进行的，使用了场辅助固态离子交换和连续波紫外线激光照射。使用不同的表征技术，证明了根据激光功率可以形成CoO或Co ₃ O ₄ NP。银NP的光学性质是金属银的特征，其不会遭受氧化。实验过程为结合Co ₃ O ₄ NPs的磁性和Ag NPs的光学性质开辟了一条新途径。
