Nanoscale 3D spatial analysis of FTO/ZnO/Ag-x films subjected to photocatalytic activity.

The study focuses on FTO/ZnO/Ag-x films (with different silver dopant levels) fabricated using the sol-gel/spin-coating technique. The optical, structural, and geometrical properties of these films were characterized through various methods, such as Photoluminescence (PL) spectroscopy, UV-visible spectroscopy, X-ray diffraction (XRD), and Field Emission Scanning Electron Microscopy (FESEM). Key findings include a reduction in transmittance and an increase in absorbance in the visible spectrum due to the interaction between silver and ZnO, enhancing photocatalytic properties.
