| dc.description.resumo | In the present paper, BaWO4:xTm3+,yPr3+ samples were synthesized by the ultrasonic spray pyrolysis process and the efect of doping on the structural and optical properties were analyzed. All XRD patterns were indexed by the scheelite-type tetragonal structure, without the presence of secondary phases, suggesting success in the Tm3+ and Pr3+ doping. The FESEM images showed than particles have sphere-like morphology with the presence of holes, irregularity, and pores on their surfaces. The bandgap of the BaWO4:xTm3+,yPr3+ sample varied between 5.50 and 5.58 eV. The doping of Tm3+ and Pr3+ resulted in a reduction in the photocatalytic activity can be linked to a decrease of efective masses ratio electron/hole and an increase in the recombination rate | pt_BR |
