Effect of Eu3+Concentration on the Luminescent Properties of SrTiO3Phosphors Prepared by Pressure-Assisted Combustion Synthesis
Advances in Materials Science and Engineering
This work presents the structural, morphological, and luminescent characterization of pure SrTiO3and SrTiO3:Eu3+powders doped with different europium atomic concentrations from 3.0 to 7.0 a.t.%. Those phosphors were prepared by pressure-assisted combustion synthesis using titanium oxide as precursor and were subjected to postannealing at 1200°C. XRD measurements indicated that undoped and Eu3+doped samples presented a single cubic crystalline phase and SEM images demonstrated that we havedoi:10.1155/2015/291230 fatcat:qgt6qkpitjhnngtkhbuyvj3l3m
