The borophosphate glasses compositions based on (64-x)P2O5-5B2O3-15ZnO-15Li2O-xX-1Sm2O3 (x = 0 & 15; X = CaF2) are prepared by melting and quenched technique. The optical and photoluminescence were obtained from the UV-Vis-NIR spectrophotometer and spectrofluorophotometer. The ground state 6H5/2 as the start transition in the absorption spectrum and the Judd-Ofelt intensity parameters (Ω2, Ω4, and Ω6) were determined. The emission spectra of borophosphate glass with CaF2 were recorded at an excitation of 401 nm which gave four peaks namely 6H5/2, 6H7/2, 6H9/2, and 6H11/2. The results of radiative properties for the 4G5/2 → 6H7/2 transition were found to be higher in the zinc borophosphate glass without fluoride. Based on these results, zinc borophosphate glass can be used as a candidate for the orange laser application. © 2023 Taylor & Francis Group, LLC.
