Judd-Ofelt Parameters of Sm3+-doped Alkali Telluroborate Glasses
Main Article Content
Abstract
Abstract: Alkali borotellurite glass (ABTe) doped with concentration of 0.5 mol% Sm3+ ions was prepared by melting method. The absorption, luminescence spectra and lifetime of ABTe:Sm3+ have been measured at room temperature. The results were analyzed using Judd–Ofelt (JO) theory, that gives the Ωλ intensity parameters, transition probabilities (AR), calculated branching ratios (βR), measured branching ratios (βmes) and stimulated emission cross-sections (σλp) for 4G5/2→6HJHHJ transitions.
Keywords: Alkali borotellurite glass, Judd-Ofelt theory.References
