Abstract


This research is intended to determine the appropriate condition for gold ruby glass production at low temperature. The effects of reducing agent (SnO2 and SeO2) concentrations on coloration of gold nanoparticle (AuNPs) in glass samples have been investigated. The glasses with chemical compositions of SiO2, B2O3, Al2O3, Na2O, CaO, K2O, Sb2O3, SnO2, SeO2 and AuNPs were fabricated by conventional melt-quench technique at 1,200°C in normal atmosphere. The results found that the red glasses were obtained by SnO2 with concentration of 0.5 wt% and SeO2 with concentration of 0.05 wt%. The color of glasses were confirmed by UV-visible spectrophotometer in the wavelength range 300-1100 nm and color coordinate in CIE L*a*b* system. Moreover, the color of glasses were obtained immediately when took the glass out of furnace without second heat treatment.
