Abstract
Dysprosium doped GexGa5Se(95−x) (x = 15–30) chalcogenide glasses were synthesized in this present work. The Vis–NIR transmission spectra, photoluminescence spectra and lifetime were measured. Glasses (x = 27.5, 29.17 and 30) doped with 0.2 wt% dysprosium ions shows relatively strong emission bands at 1146 and 1343 nm when pumped at 808 nm. The emission lifetime ranged from 440 to 540 μs. The oscillator strengths and intensity parameters Ωt (t = 2, 4 and 6) were calculated using Judd–Ofelt theory.
