The present study details the changes in photoluminescence properties stimulated by the structural changes in consequence of doping the II–VI nanocomposite thin‐film semiconductor cadmium sulfide (CdS) with the IB metallic ion Ag+. The synthesis of the matrix and doped semiconductors was performed using low‐temperature chemical bath deposition (CBD). The doping percentage of the CdS matrix was determined by energy‐dispersive X‐ray spectroscopy (EDS) with a value around 3%. The crystallographic study shows a cubic (1 1 1) preferential growth plane for the undoped material. Both X‐ray and HRTEM characterizations show the presence of a polycrystalline structure for the Ag+‐doped sample. Measurements of particle size from HRTEM micrographs confirm quantum confinement with a reduction of the average particle size from 5.46 to 4.12 nm in the doped sample. The photoluminescence study shows intense downshifted emissions in the green range of the visible spectrum. This could be due to the shallow electron traps formed by crystalline defects in the lattice, which are induced by the metallic ion. This study also shows higher‐energy emissions due to the decrease of the particle size below the effective CdS exciton Bohr radius.

“…The results indicate that CuS-Cd catalysts were more active under light irradiation, making them more suitable for use as photocatalyst materials [22]. Additionally, for all of the prepared CuS catalysts, the photodegradation e ciency of RhB dye was examined under the same experimental conditions [23]. The study found that the Cd-doped CuS thin lm was effective in degrading RhB dye molecules under sunlight irradiation, with the major absorption peak decreasing gradually and the dye turning colorless in 180 minutes.…”

The Successive Ionic Layer Adsorption and Reaction (SILAR) approach was used to fabricate Cd doped CuS nanocrystalline thin films. On the optical, structural, morphological, and electronic properties of Cd doped CuS films, the influence of a 3% Cd doping concentration was investigated. The cubic phase crystal structure of the Cd doped CuS thin was revealed by XRD measurements to be polycrystalline. The bonding of the CuS semiconductor material was verified by FTIR spectra, which also displayed the emission bands of the films. The surface morphology of the produced films changes with the concentration of Cd doping, according to the FESEM data. In the UV visible spectroscopy, a blue shift in the optical band gap was identified. Under the irradiation of sunshine, the photocatalytic activity of Rhodamine B was investigated. The degradation efficiency increased nearly 97% as Cd concentration increased.
