Effects of buffer salt concentration on the rate deposition, dominated deposition mechanism and subsequently structural, morphological, optical properties cadmium sulfide (CdS) thin films deposited by chemical bath (CBD) glass substrate were investigated. The precursors chosen to be chloride (CdCl 2 ) as source, thiourea (CS(NH[Formula: see text]) sulfur ammonium nitrate (NH 4 NO 3 ammonia complexing agent pH controller. influence NH structure, morphology, film uniformity, stoichiometry CdS was also studied X-ray diffractometer (XRD), field emission scanning electron microscope (FE-SEM), energy dispersive (EDX) spectroscope, uv–visible photoluminescence (PL) spectroscopes. XRD studies revealed that all exhibited a (002)h/(111)c preferred orientation. crystallite size increased from 20[Formula: text]nm 30[Formula: increase 0.5[Formula: text]M 2.5[Formula: text]M. morphology agglomerated spherical particles consisted smaller particles. surface at compact smooth. decreased packing density films. band gap in range 2.25–2.4[Formula: text]eV, which decrement density. PL spectra showed two peaks centered 400[Formula: 500[Formula: are attributed violet band-to-band emissions, respectively.
