Thermal Stability Of

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 3500C 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.

Ce3+-doped 0.5La2O3-2SrO-0.5Al2O3 (LSA:Ce) phosphors had been successfully synthesized using a conventional solid-state reaction method under reducing atmosphere (H2/N2 =1/5). The phase, morphologies and luminescence properties of the LSA:Ce phosphors were investigated. The emission intensity of LSA:Ce phosphors was improved by the addition of SrF2 as flux, and red shift of PL spectra peak was observed in this phosphors. Research results shown that the LSA:Ce phosphors have the potential to meet the development of white light-emitting diodes.
