Abstract

In this work, potassium aluminium phosphate (K2O-Al2O3-P2O5) glasses doped with various concentrations of samarium oxide (Sm2O3) were prepared by melt-quenching technique. The structural, optical and luminescence properties of the glass samples were characterized through the molar volume, absorption and emission spectra measurements, respectively. The absorption spectra were investigated in the ultraviolet - visible light - near infrared (UV-Vis-NIR) region from 250 to 2,000 nm. The emission spectra were observed four prominent emission bands centered at 561, 597, 643, and 704 nm by excitation at 402 nm. From the Judd-Ofelt (J-O) analysis, the J-O parameters (Ω2, Ω4 and Ω6), oscillator strength (f), radiative transition possibility (AR), stimulated emission cross section ((λp)) and branching ratio (βR) were determined to investigate the local structure and bonding in the vicinity of Sm3+ ions, including quality of a glass host for using as the optical device application.
