Judd–Ofelt analysis and photoluminescence study of akermanite-structured Sm3+ -doped Ca2MgSi2O7 phosphor synthesized by combustion synthesis followed by a solid-state reaction process is presented. PXRD confirmed the tetragonal structure with the P-4 21 m (No.113) space group. SEM, EDS, and elemental mapping confirmed the morphology and composition. The photoluminescence (PL) emission spectra indicate that the phosphor gives orange-red emissions at 603 nm attributed to 4G5/2 → 6H7/2 transition. Optimum concentration has been found to be 0.4 mol%. The CIE chromaticity coordinates are 0.57, 0.43. The branching ratio with respect to the transition, 4G5/2—6H7/2 has been found to be around 53%, suggesting it as a potential laser material in addition to its use for designing white LED phosphors.
