This article reports on the optical, photoluminescence, and radiative properties of Dy3+ doped oxyfluoride glass. The composition of glass is: 20Li2O-10AlF3-69P2O5-1Dy2O3 (LAPD). The glass has been prepared using the melt-quenching technique at 1100oC with a total mass of 15 grams in an alumina crucible. Judd-Ofelt analysis was used to determine the intensity parameters and radiative properties of Dy3+ ion in glass. The CIE 1931 chromaticity diagram coordinate is calculated to define the color coordinate of emission in a glass sample. Based on research, it is expected to produce glass material that is applied as an active laser medium and solid-state lighting materials. © 2021 Institute of Physics Publishing. All rights reserved.
