Optical and mechanical characterization of novel cobalt-based metal oxide thin films synthesized using sol-gel dip-coating method

► We synthesize cobalt-based metal oxide thin film coatings. ► They are deposited on aluminum and glass substrates via sol-gel dip-coating. ► Characterization is via XRD, SEM, AFM and XPS. ► Spectrophotometry and nanoindentation are also conducted. ► Copper-cobalt coating exhibits distinctive nano-sized and grain-like morphologies.
