| 摘 要： | 本文是载玻片上化学沉淀1000左右粗糙度的银膜,对其吡啶/KX/H_2O 体系(x=F~-,Cl~-,Br~-,I~-)的 SERS 光谱进行了实验研究。分析了不同的卤素电解质,其SERS 光谱峰值大小、位移及吸附态的变化。实验表明:适当的卤素电解质和吡啶的共吸附是产生 SERS 的必要条件。

| Abstract: | We prepared the 1000 silver film surfaces on the slide glass by Chemical deposition and have experimentally studied the SERS of pyridine/KX/water (X=F~-,CI~-,Br~-,I~-)adsorbed on the silver film substrate.By analyzing the effects of a variety of halide ions on the SERS of pyridine,we show that the cooperative adsorption of the proper halide electrolyte and pyridine is very impor- tant to the effect of SERS |
