摘要

In the present work, oxy chloro boro tellurite (OCBT) glasses were prepared with the composition 10SrO-(10-x)Al_2O_3-10BaCl_2-60B_2O_3-10TeO_2-rSm_2O (where r = 0.5, 1.0, 1.5, 2.0 and 2.5 mol%) using melt quenching tech-nique. Several optical properties were studied after thorough analysis of absorption, excitation, photo-luminescence (PL) and PL decay profiles of these glasses. Judd-Ofelt parameters evaluated from the absorption spectra are used to understand the asymmetry around the Sm~(3+) ions in the present reported glasses. An effort has been made to understand the PL properties of these glasses by evaluating the key parameters such as branching ratios and stimulated emission cross-sections and quantum efficiencies. In the process of understanding mutual interaction between the Sm~(3+) ions, Inokuti-Hirayama (I-H) method is applied. CIE color co-ordinates also measured to confirm the reddish orange emission from these glasses. From all obtained parameters, it can be suggested that OCBTSm1.0 glass is aptly suitable for reddish orange laser applications.
