Abstract
Tellurite glasses with different concentration of praseodymium (Pr3+) ion was produced by melt-quenching technique. The effect of Pr3+ concentration on optical and luminescence properties was presented. The optical absorption spectra of Pr3+ ions in glasses were recorded in the UV-VIS-NIR region. By using the integrated absorption spectrum, the Judd-ofelt parameters for Pr3+ ions were derived. The Judd-Ofelt theory was used to calculate the radiative transition probability, stimulated emission cross-section, and branching ratio of the glasses. These findings support the use of these glasses in laser and other optical device applications.
