The Effect of NaF on the Photoluminence Properties of Sammarium Ion Doped on Fluoro-Borophosphate Glass Medium

Abstract

Fluoro-borophosphate glass containing Natrium Fluoride (NaF) doped with Samarium ion 1 mol% concentration. The glass compositions based on 49P2O5-5B2O3-15ZnO-15Li2O-15NaF-1Sm2O3 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 (2, 4, and 6) were determined. The emission spectra of borophosphate glass with NaF were recorded at an excitation of 401 nm which gave four peaks namely 6H5/2, 6H7/2, 6H9/2, and 6H11/2..

Increasing quantum efficiency of erbium optical medium doped lithium fluorophosphate (EDLF) as a candidate of glass-based optical amplifier

“…Radiative properties of Erbium doped Lithium Fluorophosphate glasses.Quantum efficiency in Table5show that Er2 glass also has the highest value. Based on these results, it can be concluded that EDLF glasses is superior for use in the development of NIR optical amplifier devices [16][17][18][19][20]…”
