Estimation Of Deep-Uv And Uv Absorption Coefficients Of Selected Trace Impurities In Glasses

Glasses of the fluoride type were selected as sutable host materials for studying the uv absorption behaviour of several transition metal ions in different valence states. Based on a large glass sample collection with series of transition metal-ion-doped fluoride phosphate glasses, together with a carefully analytically determined real impurity content, the specific uv absorption spectra of the ions could be estimated using nonlinear deconvolution of bands.
