Abstract
In this work, the effect of selenium oxide on glass coloration from silver nanoparticles (AgNPs) doped in glasses were investigated. The glass samples were prepared with glass composition (63.97-x(SiO2: 10CaO: 10K2O: 15Na2O: 0.5Sb2O3: 0.5SnO2: 0.03AgNPs: xSeO2 (where x= 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5% by weight). The glasses were melted by conventional melt quench technique at 1,500 °C in open atmosphere. The results were found that, the glass samples doped with SeO2 concentration of 0.1 to 0.5% by weight showed the amber color. The color was confirmed by UV-visible spectrophotometer in the wavelength range 200-1,100 nm and from the color coordinate in CIE L∗a∗b∗ system. Moreover, the amber color was obtained immediately when take out the glass from the furnace, without second heat treatment.
