Preparation of silver particles and its application for surface enhanced Raman scattering with near-infrared excitation

Popis výsledku v původním jazyce

The preparation of silver nanoparticles through the reduction of silver ammonia complex by glucose is reported. The average of the as-prepared particle sizes varied from approx. 35 nm to 120 nm in a dependence of ammonia concentration. The mechanism of silver particle formation is dependent on the ammonia concentration. At low ammonia to silver ions ratios (1:1 and 2:1), the silver oxide particles are formed at first and subsequently are reduced by glucose. Higher ammonia concentrations are able to bindsilver ions sufficiently without forming silver oxide as an intermediate and in these cases are silver particles generated through direct reduction of [Ag(NH3)2]+ by glucose. The obtained silver particles were tested in surface enhanced Raman scatteringexperiments with infrared laser excitation (1064 nm). The adenine was used as a model analyt for evaluation of the surface enhancement efficiency. Before surface enhanced Raman measurements, sodium chloride of a resulting concentration e
