摘要
SrY(2)O(4)belongs to the family of AB(2)O(4)(A = alkaline earth metal, B = rare earth element) type spinel oxides. SrY(2)O(4)is an inter oxide in SrO and Y(2)O(3)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 SrY(2)O(4)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 SrY(2)O(4)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 SrY(2)O(4)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 SrY(2)O(4)are proposed. This review article gives a complete summary for the drawbacks and current challenging issues of SrY(2)O(4)phosphors, which can give potential sprout for future work.
