Photoluminescence (PL) of Eu3+ was studied in SrIn2O4 host lattice. A complete solid solubility of Eu3+ has been found in the series SrIn2−xEuxO4 [x=0–2.0]. The phase formation at a relatively low temperature and in a very short duration was achieved by combustion synthesis (CS). Concentration quenching of luminescence has been observed in SrIn2−xEuxO4 [x=0.1–2.0] and the critical concentration for maximum emission was found to be with x=0.3. In order to find the role of crystallite size on the PL properties of SrIn2O4:Eu3+, the results obtained with phosphors synthesized by solid state reaction (SSR) and CS methods were compared.
