我们通过检测金的TPI-PL和罗丹明6G吸附在纳米粒子上的拉曼散射，观察到了金纳米球聚集体的近场图像。分析结果与表面增强拉曼散射的局域拉曼活性中心(热点)有关。
We observed near-field images of aggregates of gold nanospheres, by detecting TPI-PL from gold and Raman scattering from Rhodamine 6G adsorbed oil the nanoparticles. The results were analyzed in relation to the localized Raman active site (hot Spot) of surface-enhanced Raman scattering,.
