使用雾化学气相沉积法在石英玻璃基板上形成银颗粒。沉积的颗粒由同心分布的纳米至亚微米颗粒组成。该颗粒是多晶的，并且发现其化学状态是金属银。通过测量银颗粒上的罗丹明6G（R6G）溶液作为表面增强拉曼散射（SERS）的活性板，可以清楚地检测到浓度低至10−8 mol l−1 的R6G 对应的SERS 信号峰。此外，SERS 强度随着 R6G 浓度的降低而线性降低。
Silver particles on the quartz glass substrate were formed using the mist chemical vapor deposition method. The deposited particles were comprised of nano to sub-micron particle that were concentrically located. The particles were polycrystalline, and the chemical state was found to be metallic silver. By measuring rhodamine6G (R6G) solution on the silver particles as an active plate for surface enhanced Raman scattering (SERS), the peaks of the SERS signal corresponding to R6G were clearly detected down to the concentration of 10−8 mol l−1. Additionally, the SERS intensities linearly decreased with the decrease in R6G concentrations.
