We investigated the effect of annealing time on the structure and optical properties of SrWO4:Eu3+ powders prepared by the non-hydrolytic sol-gel method and heat treated at 800 °C for 2, 4, 8 and 16 h. Thermogravimetric and differential thermal analyses revealed that SrWO4:Eu3+ powders were obtained at about 800 °C. X-ray diffraction patterns and Rietveld refinement data confirmed that all powders...
