| Abstract: | This work presents the influence of europium dopant on optical properties of Sr2SnO4:Eu3+ powders fabricated by a facile low temperature method. Powders were obtained from the same amounts of Eu3+ doping into the different concentrations of Sr(NO3)2. Powders were examined by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), and photoluminescence (PL). SEM measurements different Eu concentrations in fabricated powders was determined to found different morphologies. XRD analysis revealed the existence of crystalline Sr2SnO4 in the form of tetragonal and the diffraction intensity was remarkably changed. PL studies showed a red luminescence of Sr2SnO4:Eu3+ powders. The intensity of luminescence increased with better crystallinity. This approach provides economically viable route for large-scale synthesis of this kind of nanopowders. |
