Source abstract
Abstract
In this paper, CdZnS nanocrystalline films have been deposited by using chemical bath deposition (CBD) technique on glassy substrates. After deposition process, the films were annealed at different period of time (30, 60 and 120 minute) using thermal furnace. Optical properties of CdZnS films such as absorbance and optical band gap, have been investigated. From this measurements, the bandgaps energies were found to be 3 eV, 2.69 eV, 2.5 eV and 2.2 eV for (0, 30, 60 and 120 minute) respectively. The optical energy gap decreased as the annealing time increased. In this study, the influence of annealing time on the structure, optical, and surface properties of CdZnS thin films was examined, and the results were thoroughly discussed. This demonstrates their potential applicability in optoelectronic and photovoltaic devices, among other things.
