SrY2O4 belongs to the family of AB2O4 (A = alkaline earth metal, B = rare earth element) type spinel oxides. SrY2O4 is an inter oxide in SrO and Y2O3 pseudo-binary phase diagram. It has attracted immense interest as a promising host lattice owing to its thermal and chemical stability. The luminescent characteristics of SrY2O4 phosphors make them promising candidates for field emission displays. In the present review article, recent progress in the synthesis and luminescent properties of bare and doped SrY2O4 phosphors are reviewed. In the first part, different synthesis routes and their resultant outcomes are discussed. Then, the downconversion and upconversion luminescent characteristics of undoped and doped SrY2O4 phosphors are reviewed. The effect of site occupancy, morphology, reaction conditions, different excitation wavelengths, dopant concentrations, and energy transfer mechanisms are explained in detail. In the end, challenges and future scope in luminescence and synthesis of SrY2O4 are proposed. This review article gives a complete summary for the drawbacks and current challenging issues of SrY2O4 phosphors, which can give potential sprout for future work.
