| -- | The study focuses on the deposition and characterization of thin layers of cobalt oxide (Co3O4) developed using the pneumatic spray technique. A system was developed for the deposition of materials using a compressor on a heated surface, with the precursor concentration and substrate temperature being variables that were varied. The X-ray diffraction analysis revealed polycrystalline films with a spinel-like structure, exhibiting multiple growth directions. The size of crystallites exhibited a direct correlation with both temperature and molarity. The surface morphology exhibited homogeneity and comprehensive coverage. A thorough examination of the films' optical properties revealed their capacity for absorption across the UV-Visible and NIR spectrums. Transmittance spectra revealed two fundamental absorption fronts in the visible region, indicating potential degeneration of the valence band. Electrical characteristics exhibited increased conductivity. |
