Abstract: The present invention relates to a simplified spray pyrolysis process for the fabrication of yttrium (Y-doped zinc oxide (ZnO) thin films exhibiting enhanced photoeatalytie and antibacterial properties. The invention comprises preparing an aqueous precursor solution containing zinc acetate and a yttrium precursor, followed by deposition onto heated glass substrates under ambient atmospheric conditions without the use of vacuum systems or carrier gases. The incorporation of yttrium into the ZnO lattice at controlled concentrations produces highly crystalline thin films with a hexagonal wurtzite structure, modified optical band gap, enhanced visible-light absorption, optimized defect density, and characteristic tetrapod chain-like surface morphology. The engineered thin films demonstrate superior photocatalytic degradation of organic dye pollutants through efficient generation of electron-hole pairs and reactive oxygen species under ultraviolet in-adiation. The disclosed process provides a simple, cost-effective, reproducible, and scalable route for manufacturing multifunctional semiconductor thin films suitable for wastewater treatment, self- cleaning surfaces, environmental remediation and related industrial applications.
