FABRICATION AND CHARACTERIZATION STUDIES OF LITHIUMBORATE RUBY GLASSES CONTAINING GOLD NANOPARTICLES
Journal Title: International journal of research -GRANTHAALAYAH - Year 2017, Vol 5, Issue 4
Abstract
Glasses containing Au nanoparticles have been synthesized in the base glass of composition 30Li2O–70B2O3 using gold chloride (HAuCl4.3H2O) as a dopant. The characteristic ruby color has been observed which is attributed due to surface plasmon resonance of the Au nanoparticles. The hue of the color increases with the increase of concentration of the dopant. Presence of the gold nanoparticles has been confirmed by studying the optical absorption spectra in the visible range which show a characteristic absorption peak at ~560nm. XRD and SEM studies show that the addition of Au increases the kinetics of growth and crystallization. ESR studies indicate that the electronic state of gold is either Au0 or Au+ .
