Spectroscopic studies and lasing potentialities of Sm3+ ions doped single alkali and mixed alkali fluoro tungstentellurite glasses

CBA Devi, K Swapna, S Mahamuda… - Optics & Laser …, 2019 - Elsevier
Samarium ions doped single alkali and mixed alkali fluoro tungsten tellurite glasses
prepared by employing melt quenching technique were characterized by using various
spectroscopic techniques such as optical absorption, excitation, emission and decay
spectral studies. From the absorption spectral features, the optical band gap energies have
been evaluated. By applying the Judd-Ofelt (JO) theory to the measured oscillator strengths
(f exp), the best fit JO parameters are evaluated and used further in evaluating the radiative …
