Influence of various chloride ion concentrations on silver nanoparticle transformations and effectiveness in surface enhanced Raman scattering for different excitation wavelengths

Popis výsledku v původním jazyce

The effect of six various chloride ion concentrations (25, 50, 100, 200, 400, and 800 mM) on timedependence and surface enhanced Raman scattering (SERS) signal intensity was investigated for silver nanoparticles (28 nm) with a high monodispersity and long time stability. The experiments were performed using three lasers with excitation wavelengths in the visible region (532 nm, 633 nm, 780 nm). Adenine was used as a model analyte. The treatment procedure, when the various sodium chloride solutions addedto silver nanoparticles, led to an enhancement in the Raman signal at all studied concentration levels of sodium chloride. Nevertheless, low-concentration chloride ions differently influenced the time course of enhancement efficiency contrary to high-concentration chloride ions. The final concentration of chloride ions equal to 25 mM did not have any pronounced influence on the silver particle sizes and morphologies. The final concentration of chloride ions varying from 50 to 200 mM led
