Optical and structural studies of ZnO thin film prepared by electrodeposition method

Zinc oxide (ZnO) is versatile material and has attracted considerable attention for its several applications in electronics, optoelectronics, bioelectronics etc. in the form of thin film, nanoparticles, nanorods, nanotubes, nanobelts, nanodots and nanowires. ZnO is a direct band gap material with high excitation binding energy. The property of the ZnO differs in respect to its size, shape and dimensions. In this paper, we present the experimental investigation of ZnO thin film prepared by electrodeposition method. The film was deposited on the FTO glass substrate using three-electrode configuration dipped in the mixed solution of zinc chloride, potassium chloride and deionized water. The as-prepared film was thermally treated at 400° C and later its optical and structural properties were studied.Zinc oxide (ZnO) is versatile material and has attracted considerable attention for its several applications in electronics, optoelectronics, bioelectronics etc. in the form of thin film, nanoparticles, nanorods, nanotubes, nanobelts, nanodots and nanowires.
