Electrochemical and Structural Behavior of Bi Doped ZnO Materials Obtained with Solvothermal Synthesis Method

In this study, Bi-doped ZnO and undoped ZnO nanomaterials have been synthesized by the solvothermal reaction method. The effect of Bi doping on the structural and electrochemical properties has been investigated by X-ray diffractions (XRD), X-ray photoelectron spectroscopy (XPS) and, scanning electron microscopy (SEM). As seen from X-ray diffraction spectra performed on the bulk material, it has been clearly observed that both Bi doping changed the preferred orientation of the nanopowder as (101) and Bi+3 ions were expectedly entered the lattice. Furthermore, this result has been supported by photoelectron spectra. Scanning electron microscopy images have shown the shapes and distributions of nanostructures of the samples. As a result, it is thought that Bi doping is suitable for obtaining p-type conductivity in ZnO materials for the experimental processes we applied to samples in the study.
