In this work, Eu 3+ -doped barium sodium borate oxide and oxyfluoride glasses were fabricated by melt-quenching technique for investigated their physical, optical, photoluminescence and radiative properties. The emission spectra, observed under the 394 nm, show the emission band corresponding to the transitions of  5 D 0 → 7 F 1  (590 nm),  7 F 2  (613 nm),  7 F 3  (652 nm) and  7 F 4  (701 nm). The most intense emission band is the  5 D 0 → 7 F 2  transition at 613 nm. The emission light is shown the reddish-orange color according to the framework of CIE 1931 color space. The Judd-Ofelt analysis confirmed the potential for using the glass samples in this work for use as photonic applications. The results from the emission spectra and radiative properties show that the oxyfluoride glass sample has more lasing potential than the oxide glass sample.
