FEATURES OF SYNTHESIS THE PEROVSKITE-LIKE OF STRUCTURES LIKE MSnO₃(M = Ba, Sr, Ca) AND RESEARCH OF THEIR LUMINESCENT PROPERTIES

Abstract

The review of the existing methods of synthesis of structures of type MSnO3 (M = Ba, Sr, Ca) is made. Formation process the phases of perovskit BaSnO3, SrSnO3, CaSnO3 received by solid-phase synthesis is experimentally investigated. Features of synthesis of these structures are revealed. It was produced doping rare-earth metal Eu ions stannate. It is revealed that in structures (Sr1-хEuх)SnO3, (Ba1-хEuх)SnO3 and (Ca1-хEuх)SnO3 received by solid-phase synthesis observe a luminescence in visible area of a range. The assumption is made that synthesizing the above connections from solutions, it is possible to achieve the best interaction of components, and, as a result, the best indicators of intensity of a luminescence.
