Abstract

In the current study, pristine and Co@CdS nanocrystalline thin films were fabricated on glass substrates by sol–gel spin coating technique. The structural and optical properties of fabricated films were systematically evaluated. The fabricated films are polycrystalline in nature and have a cubic structure. An investigation of the structure reveals that Co ions have been fully integrated into the CdS lattice. Crystallite size, microstrain, and lattice parameters were calculated using the Debye–Scherrer formula. The crystallite size of the pristine CdS thin films was observed to be 12.05 nm and decreased to 9.73 nm with Co-doping. Also, the microstrain and dislocation density of the films increased with an increase in Co-doping concentration. The 1-LO and 2-LO Raman peaks were found to be shifted toward the lower frequency side. Transmittance, refractive index, and extinction coefficient were examined to identify the changes in optical characteristics caused by Co-doping. The doping process improves the energy bandgap of the CdS nanocrystalline thin film which was in the range of 2.46 to 2.56 eV. The doping also alters the photoluminescence characteristics of CdS, leading to a change in peak toward shorter wavelengths for Co@CdS. The RMS roughness and average grain size of the films decreased with doping. These findings suggest that synthesized films could be a potential material used for optoelectronic applications.
