Abstract
AbstractThe visible spectral absorption at 390 nm of a dear tight-yellow silver subcolloid partly shifted to 510-550 nm due to the adsorption of phenylmercaptotetrazole (PMT) or mercaptobenzo- thiazole (MBT), which produced an enhanced surface Raman scattering effect.The normal Raman spectra (NRS) of solid PMT and MBT and their surface enhanced Raman spectra (SERS) on the surface of the silver subcolloidal particles are reported and compared. The adsorption of halide ions competes with that of PMT and MBT. However, halide ions have a completely different influence from PMT and MBT on the spectral absorption of the silver sol.
