“…Broad diffractions peaks represent the nano‐crystallinity of the films rather than the deposition of amorphous material, as reported previously by several authors . The average crystallite size in the case of ZnS deposition was 9.09 nm and is close to that observed by Man and Lee .…”

“…The role of complexing agent along with pH of the solution has crucial importance in deposition of oxygen free ZnS thin films by CBD . Optimized conditions for the growth of nanocrystalline ZnS thin films by CBD have been reported recently by the authors . Herein, we report a simple, cost effective and reproducible method to deposit monophasic and nanocrystalline thin films of FeS, ZnS, and ZnO on glass substrates without seed layers.…”

FeS, ZnS, and ZnO nanostructured thin films have been deposited by Chemical Bath Deposition (CBD), a simple and cost effective technique. These materials with different morphologies such as nano‐flakes, nanoparticles and nanorods for FeS, ZnS, and ZnO, respectively were deposited onto the glass substrates. The crystallite sizes have been estimated from Scherrer's equation and were found to be 14 nm for nano‐flakes of FeS, 9.09 nm for nanoparticles of ZnS, and 49 nm for nanorods of ZnO. The average values of the band gaps were found to be 1.97, 3.43, and 3.74 eV for FeS, ZnO, and ZnS thin films, respectively. These nanostructured semiconducting materials have wide applications in advanced optoelectronic devices.

“…Un-doped and iron doped ZnS thin films were deposited on glass substrates by the CBD method at acidic value of pH (4.0) [25]. Appropriate quantities of zinc chloride, iron chloride, thioacetamide and urea were weighed according to the stoichiometry and were dissolved in deionized water to make 0.15, 0.15, 1 and 5 M solutions respectively.…”

“…The growth in all the cases is quite similar resulting in agglomerated grains/clusters except enough variation in size but slight variation in shape. Here, it is worth mentioning that, the morphology of thin films was controlled by the optimized growth conditions [25] instead of using any additional surfactant or capping agent [31][32][33]. The deposition of ZnFeS on glass substrates would be demonstrated by nucleation as a function of deposition time rather than by the clusters and clusters deposition.…”

a b s t r a c tThe nanocrystalline thin films of Fe-doped ZnS were deposited onto glass substrates by a chemical bath deposition (CBD) method. X-ray diffraction patterns reveal the formation of cubic zinc blende phase of ZnS. The incorporation of iron in ZnS lattice changed the lattice parameters of the ZnS structure. The purity of doped films was confirmed by the absence of secondary phases or iron clusters. SEM images show the growth of almost spherical clusters with slight change in size between un-doped and Fe-doped ZnS samples. The M-H curves indicate that doped ZnS thin films exhibit room temperature ferromagnetism. The magnetization properties as a function of applied field and doping concentration were studied in detail. The density functional calculations were performed using Full Potential Linearized Augmented Plane Wave (FP-LAPW) approach as is employed in Elk-code. The strong p-d hybridization between sulfur and iron resulted in ferromagnetic stable state and half-metallicity. The half-metallic iron doped ZnS thin films have potential applications in future spintronic devices.

“…The occasional thin film reports include the synthesis via spray pyrolysis [11], pulsed laser deposition [12] and chemical bath deposition [13,14]. Other methods used for the synthesis of Zn-Co-S films and nanocrystals include: aqueous method [15], refluxing technique [16], precipitation method [17] and hydrothermal approach [18,19]. Recently cobalt has been found to be a prospective doping material in ZnS as Co 3+ and Co 2+ doping can result into enhanced photoluminescence [1].…”
