Therefore we have optimized the experimental system and the working status of instrument.2 The near-field SERS spectra and images for the [Ru_3]~(2+) molecule adsorbed on silver nanoparticle substrate were achieved. Based on the results, some specific phenomena for near-field SERS were found. By observing the near-field SERS spectra collected at different location at the nano-scale, the different spectral characteristics which are caused by the local environmental differences of molecules have been found. On the substrate, the highly SERS active sites are much more than SEF hot spots, and the distribution of them is not entirely consistent. This phenomenon could be explained by the influences of several factors including the different enhancement efficiencies existed for SERS and SEF, the quenching effects for fluorescence by the metal substrate and metal-coated tip, and the presence of different numbers of probing molecules in SERS and SEF.3 It is of interest that the near-field and far-field SER spectra demonstrate several distinctively different spectral features.

由于SNOM与SERS的结合在技术上将面临很多实际困难，例如近场激发信号极其微弱、纳米级微弱光谱的收集对实验精度和环境稳定性的苛刻要求等，因此我们对实验体系和仪器工作状态分别进行了优化。2获得了银纳米粒子SERS基底上[Ru_3]~(2+)分子在纳米尺度下的近场SERS光谱和图像，从中可以发现一些近场SERS效应特有的现象：通过观察不同位置得到的近场SERS光谱可以发现，在纳米尺度下，由于分子所处局域环境不同而体现出不同的光谱特征；此基底具有极高SERS活性的位点远多于表面增强荧光热点，且两者的分布并不完全一致。
