Study on the Morphology and Thermal Stability of Li₂SrSiO₄: Tb³⁺ Materials

Article Preview

Abstract:

A series of Tb³⁺-doped Li₂SrSiO₄:Tb³⁺ phosphors were prepared by high temperature solid state reaction. The morphology and the thermal stability of Li₂SrSiO₄:Tb³⁺ phosphors were discussed by SEM and PL measurements, respectively. The results showed that the morphology of Li₂SrSiO₄:Tb³⁺ was changed from flower-like to rod-like with increasing Tb³⁺-doped content. Moreover, the emission intensity measured at 350 ⁰C almost maintain with constant compared with that measured at room temperature. The results showed that Li₂SrSiO₄:Tb³⁺ phosphor might be a potential phosphor for white light-emitting diodes.
