This study investigates the development of luminescent and self-cleaning paints based on ZnO/TiO₂ nanocomposites. The potential of utilizing the photocatalytic and optical properties of ZnO and TiO₂ nanostructures for producing high-performance functional coatings was analyzed. The synergistic interaction between the nanocomposite components was found to enhance luminescence intensity under ultraviolet irradiation and improve the self-cleaning ability of the coating through the photocatalytic degradation of organic contaminants. The obtained results demonstrate that ZnO/TiO₂-based nanocomposite paints are promising materials for applications in construction, decorative coatings, and environmentally friendly functional surfaces. The combination of luminescent and photocatalytic properties contributes to the development of advanced multifunctional coating systems with improved durability and environmental performance.
