Abstract

This study investigates Ho-doped tin disulfide (Ho-SnS₂) thin films prepared via spray coating, focusing on varying Ho doping levels (0 at. %, 2 at. %, and 4 at. %). Structural analysis through XRD and SEM showcased enhanced crystallinity and morphology in Ho-SnS₂ films. Raman and XPS studies provided insight into the film's composition and chemical states. The antibacterial properties of the films were investigated using a bacterial growth inhibition assay. The results showed significant antibacterial activity against Gram-positive and Gram-negative bacteria, highlighting the potential applications of Ho-SnS₂ thin films in antibacterial coatings. Ho-SnS₂ films exhibited superior photocatalytic activity and antibacterial properties compared to SnS₂ films, attributed to efficient charge separation. DFT analysis proposed a mechanism for the antibacterial activity. These findings highlight the efficacy of the spray coating technique in producing Ho-SnS₂ films and the potential of Ho-SnS₂ films for diverse applications like photocatalysis and antibacterial coatings.
