Samarium-Doped ZnO Nanoparticles Show Enhanced Crystal Violet Degradation and Antifungal Activity

Researchers have investigated the impact of samarium (Sm) doping on zinc oxide (ZnO) nanoparticles, focusing on their structural properties and photocatalytic capabilities under visible light. The study specifically examined the degradation of crystal violet dye, a common pollutant, and the antifungal activity of these modified nanoparticles. The findings indicate that introducing samarium into the ZnO structure significantly influences its performance in both applications. The doping process alters the crystal structure of ZnO, which in turn enhances its ability to absorb visible light. This improved light absorption is crucial for activating the photocatalytic process. Consequently, the Sm-doped ZnO nanoparticles demonstrate a more effective degradation rate for crystal violet dye compared to undoped ZnO. Furthermore, the research explored the antifungal properties of the doped nanoparticles, suggesting potential applications in combating fungal infections. The enhanced visible-light-driven photocatalysis and antifungal activity highlight the potential of Sm-doped ZnO as a versatile material for environmental remediation and biomedical uses.
