Abstract
In this research, pure and 4%, Mn-doped thin films of cadmium sulfide (CdS) were synthesized using a 2-hour hydrothermal process. The effect of adding the dopant concentration on thesamples' structural, morphological, and optical characteristics were investigated. The ultraviolet-visible-NIR spectrophotometer was used to investigate the optical properties. UV-Vis experiments lowered the optical bandgap with an add Mn percentage. Their optical bandgap was 2.38 eV for undoped thin films and 1.81 eV for 4% doped Mn-CdS thin films. UV-Vis spectroscopy data are in agreement with PL. FE-SEM imaging revealed morphological changes caused by the inclusion of Mn in CdS thin films. FE-SEM displays images of undopedCdS,which appear to be Nanoparticles. Morphology of the thin films has shown that the average grain size increases by the agglomeration of Nano-grains, which become clusters of particles after Mn+2incorporation. In addition, The XRD pattern revealed that prepared samples H (002)/C (111) as hexagonal and cube phases have a preferential orientation. The increase in the main diffraction peak (002) intensity with increasing Mn concentration revealed the substitution of Mn+2 with Cd+2 in the lattice. The crystallite size increased from10.74 to 11.67 nm with an Mn percentage.
