The glass formula of 20Li2O+10AlF3+2.5CaF2+(66.5-x)P2O5+xGd2O3+1Eu2O3 (PLACEu1Gdx), where x = 2,4,6,8,10 mol% have been prepared by conventional melt-quenching technique. These glasses' optical absorption, photoluminescence, decay time, and radioluminescence have been measured at room temperature. Judd-Ofelt's (J-O) analysis of PLACEu1Gd8 has been investigated and the magnitude of parameters follows the trend as Ω2>Ω4>Ω6. The important laser parameters such as radiative properties are calculated using J-O parameters and luminescence spectra. The decay time with the transition from the 5D0 level was estimated under 274 nm and 394 nm excitation using bi-exponential fitting. CIE coordinates, CCT and intensity ratio have been calculated for glass samples. The integral scintillation efficiency of PLACEu1Gd8 is 31% compared with BGO crystal. The PLACEu1Gdx glasses are promising for laser medium and x-rays detection material applications. © 2022 Elsevier Ltd
