摘要

Mn-doped CdS thin films with different doping concentrations were synthesized using the Successive Ionic Layer Adsorption and Reaction (SILAR) technique. The structural, optical, and morphological properties of the prepared films were systematically investigated. X-ray diffraction confirmed a cubic crystalline structure with a preferred (111) orientation, and Mn incorporation influenced crystallite size and defect density. Optical absorption studies showed a red shift in the absorption edge with increased Mn content, resulting in a band gap reduction from 2.49 (pure CdS) to 2.44 eV (15 at.% Mn-doped CdS). FTIR analysis verified the presence of Cd–S bonding and Mn incorporation into the lattice. Scanning electron microscopy revealed uniform morphology. These results indicate that Mn doping effectively tailors the structural and optical properties of CdS thin films. This study demonstrates a low-cost SILAR approach to Mn-doped CdS thin films with tunable structural and optical properties, highlighting their potential application as buffer layers in thin-film solar cells.
