Producing BiI/BiOI Thin Films via Chemical Bath Deposition

In this paper, we tried to describe a different method for producing BiI and BiOI thin films, which is chemical bath deposition on glass substrates. Structural and optical properties of BiI and BiOI thin films were examined using X-ray diffraction (XRD), scanning electron microscope (SEM), and UV-VIS measurements. Film thicknesses of the films were measured by Atomic Force Microscope (AFM). Chemical analysis by EDX was performed with an EDX spectrometer attached to SEM. Various concentrations of bismuth and iodine solutions were tested to determine optimum parameters for BiI and BiOI productio...
