In this work, we present an ordered substrate obtained by the vertical deposition of SiO2 microspheres coated with a gold layer to increase the sensitivity of the Laser-Induced Breakdown Spectroscopy (LIBS) method for analysis of TiO2 nanoparticles. Plasmonic-ordered-structure-enhanced-LIBS method (POSELIBS) provides enhancement due to localized surface plasmon resonance of an ordered substrate.

基于 SiO2 微球上金膜的有序衬底,用于提高激光诱导击穿光谱法在纳米颗粒研究中的灵敏度
在这项工作中,我们提出了一种通过垂直沉积涂有金层的 SiO2 微球获得的有序衬底,以提高激光诱导击穿光谱 (LIBS) 方法分析 TiO2 纳米颗粒的灵敏度。等离子体有序结构增强 LIBS 方法 (POSELIBS) 由于有序衬底的局部表面等离子体共振而提供增强。
