Abstract: 

Glasses have been prepared by melt-quenching technique. Optical absorption and emission spectra of 0.5 mol% Dy3+doped lithium– sodium and lithium-potassium chloroborate glasses havebeen recorded. The amorphous nature of glass matrix was confirmed by XRD. Free-ion Hamiltonian model and Judd - Ofelt theory have been used to analyze the energy level scheme and the spectral intensities of Dy3+ ion in these glasses. The intensities of f-f transitions are parameterized in terms of Judd-Ofelt (JO) intensity parameters Ωλ (λ = 2, 4 and 6). The JO parameters obtained have been further used to predict radiative propertiessuch as total radiative transition probabilities (AT), radiative lifetimes (τR), branching ratios (βR) and integrated absorption cross-sections (Σ)forall the excited states of theseDy3+doped glasses. Photoluminescence spectra consist of two bands due to 4F9/2→ 6H15/2(blue) and 4F9/2→ 6H13/2(yellow). The stimulated emission cross-sections(σp)are also evaluated for all theobserved emission transitions. Optical band gaps (Eopt) for both direct and indirect transitions are reported. The rare-earth doped glasses with variousvisible emissions are useful for developing new color light sources, fluorescent display devices, UV-sensor and tunablevisible lasers.
