dc.description.resumoThe study of photocatalysis and photoluminescence in semiconductors has shown promise for applications in wastewater treatment and light-emitting diodes, respectively. In this work, Bi2-xPrxWO6 powders (x = 0, 0.01, and 0.03) with the addition of beetroot extract were synthesized by microwave-assisted hydrothermal method at 150 °C for 60 min. The X–ray diffraction results indicated the formation of an orthorhombic structure and showed that the addition of the Pr3+ dopant and beetroot extract did not result in the appearance of additional phases. Using the X-ray photoelectron spectrometer, the presence of praseodymium in the Pr3+ state was confirmed, indicating substitutional doping with Bi3+. Morphology predominantly consists of flower-like microspheres, which are composed of numerous thin nanosheets. The bandgap energy varied between 3.56 eV and 3.65 eV, influenced by the structural modifications caused by the incorporation of Pr3+ ions and beetroot extract into the Bi2WO6 matrix. The optical properties showed promise for light-emitting diode applications, with correlated color temperature values close to those of pure white (5500 K). The results of the photocatalytic tests indicate that the powders containing 100 % beetroot extract by volume and 0.03 of Pr3+ presented the best performance, degrading 99.21 % and 98.11 % of the methylene blue and crystal violet dyes, respectively. Finally, the structural stability of the powders was maintained after three reuse cycles, with a decrease in efficiency of 2.39 % for methylene blue and 10.67 % for crystal violet, confirming that the material can be recycled multiple times
