Spectral Properties of Cu^{2 +}, Ni^{2 +}, Co^{2 +}, Mn^{2 +} & Cr^{3 +} Ions Doped B₂O₃-BaO-LiF Glasses

Abstract

Brightly colored and more transparent optical glasses in the general chemical composition of B₂O₃-BaO-LiF (abbreviated as BBLi) with certain transition metal ions (each in 1 mol %) as the dopant ions have been prepared to investigate their optical absorption and photoluminescence spectra. We have measured absorption spectra of five transition metal (Cu^{2 +}, Mn^{2 +}, Co^{2 +}, Mn^{2 +} and Cr^{3 +}) ions doped glasses and while measuring the emission spectra, only for Co^{2 +}, Mn^{2 +} and Cr^{3 +} ions doped glasses have been obtained and therefore these spectral features are reported here with appropriate electronic transition assignments.
