Influence of titanium ions on optical properties of AF-PbO-B2O3 glasses

AF-PbO-B2O3 (where A=Li, Na, K) glasses containing different concentrations of TiO2 ranging from 0 to 0.6 mol% were prepared. A variety of spectroscopic studies viz. infrared spectra, optical absorption, ESR spectra and thermoluminescence have been carried out as a function of titanium ion concentration. The results of these studies have been analyzed in the light of different oxidation states of titanium ions. The comparison of the results of three series indicate the lithium series glasses are the better candidates for the practical applications.
