ESTIMATION OF DEEP-UV AND UV ABSORPTION-COEFFICIENTS OF SELECTED TRACE IMPURITIES IN GLASSES

Glasses of the fluoride phosphate type were selected as suitable host materials for studying the uv absorption behavior of several transitio n metal ions in different valence states (Fe2+/3+, Cu+/2+, Pb2+, Ni2+, Cr3+). Based on a large glass sample collection with series of transi tion metal-ion-doped fluoride phosphate glasses together with a carefu lly analytically determined real impurity content, the specific uv abs orption spectra of the mentioned ions could be estimated using nonline ar deconvolution of bands.
