Sm³⁺-doped SrIn₂O₄ phosphors were prepared by a solution combustion method. The synthesized phosphors were characterized using powder XRD. The excitation and emission spectra of Sm³⁺-doped SrIn₂O₄ materials were analyzed at room temperature. SrIn₂O₄:Sm³⁺ phosphor emits 568–578, 606–617, 660, and 720 nm light under ultraviolet excitation of 300 nm. The photoluminescence properties of the synthesized phosphors with different Sm³⁺-doping concentrations were investigated. The optimum concentration of Sm³⁺ ion in SrIn₂O₄ was found to be 0.02 mol.
