The influence of chemical composition on
color of lead-silicate glasses caused by gold nanoparticles
Abstract
The influence of lead content in the K2O–PbO–SiO2
system on the color of glasses caused by plasmon resonance of gold
nanoparticles is discussed. It has been shown that in glasses with high lead
content a longer time of secondary heat treatment (“striking”) and high
temperature affect a hypsochromic shift of plasmon frequency in UV-vis
spectra, while for the remaining compositions a bathochromic effect is
observed. This is explained by the change in the structural role of lead in the
silicate matrix.
Key words: lead silicate glasses, gold
nanoparticles, plasmonic resonance, electronic spectroscopy, luminescence
spectra.
