Samarium doped magnesium phosphate glass having a composition of [P 2O 5] 50-x-[MgO] 50-[Sm 2O 3] x, with 0≤:x≤:4 mol% were prepared by melt-quenching method. The emission spectra were recorded using the photoluminescence spectrometer in the range of 540-730 nm at room temperature after being excited at 403 nm. It was found that the emission spectrum of Sm 3+consisted of four emission bands at ∼559.76 nm, ∼597.32 nm, ∼641.55 nm and ∼705.57 nm which were assign as a transition of 4G 5/2→ 6H 5/2, 4G 5/2 → 6H 7/2, 4G 5/2→ 6H 9/2 and 4G 5/2→ 6H 11/2 respectively. The transition of 4G 5/2→ 6H 7/2 is detected as the strongest orange (597.32 nm) luminescence peaks thus dominates the transition.
