Luminescent Properties of Ca_1-xBa_xSnO₃: Eu³⁺, Dy³⁺ Composites Prepared by Coprecipitation

Abstract:

A series of Eu³⁺, Dy³⁺actived Ca_1-xBa_xSnO₃ phosphors were synthesized by coprecipitation method. The structure, morphology and fluorescence property of phosphors were investigated by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and fluorescence spectroscopy. SEM results showed that the as-prepared phosphors are smooth and uniform with the cubic morphology. The incorporation of a small amount of Ba to CaBaSnO₃ improved the emission characteristics. Fluorescence spectrum showed the emission intensity is the best with the incorporation of Ba²⁺ (x = 0.3), when calcination temperature is 900°C.
