Influence of Calcium Fluoride on the Radiative Properties of Sm³⁺ Doped Zinc Borophosphate Glasses

Abstract

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 ⁶H_5/2 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 ⁶H_5/2, ⁶H_7/2, ⁶H_9/2, and ⁶H_11/2. The results of radiative properties for the ⁴G_5/2 → ⁶H_7/2 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.
