“…The decrease of the band gap is related to the increase of ZnS crystallite size. Our results are consistent with the reported CBD ZnS optical band gap values ranging from 3.62 to 3.93 eV[14][15][16][17]21].Fig.7 illustrates the room temperature PL spectra of the CBD ZnS single layer thin films deposited for different durations. The spectra show that the PL intensity is dependent on deposition time.…”

“…Various methods have been used to prepare ZnS thin films, such as magnetron sputtering [6], plasma-assisted metalorganic chemical vapor deposition [7], chemical bath deposition (CBD) [1][2][3][4][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], electro-deposition [23] and pulsed-laser deposition [24]. Among these methods, the CBD technique is usually employed because it is very simple, cost effective, reproducible and can be used to deposit large area at moderate temperature.…”

“…In the chemical bath deposition for the ZnS thin films, there are many parameters to be controlled, including Zn source, S source, complexing agent [25][26][27], pH of the solution [3,8,12], bath temperature [13], stirring speed [22]and deposition time [1,3,11,14,15,16,28,29].…”

“…chemical bath deposition but without a surface capping agent. In addition, several reports have been published on optical studies of metal (Cu, Mn, Ni and Co) doped ZnS [17][18][19][20][21] thin films by the CBD method. However, to the best of our knowledge, magnetic studies on iron doped CBD ÀZnS thin films have never been reported before.…”

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.

“…Zinc Sulphide (ZnS) belongs to a typical n-type semiconductor of II-VI semiconductors family [1][2][3]. It has a wide direct band gap of 3.6 eV and exciton binding energy of 40 meV at room temperature [4]. Because of its broad band gap energy, it is mostly used in blue shift light emitting diodes [5,6].…”

Nanocrystalline ZnS thin films incorporated onto glass substrates by chemical bath deposition method were investigated by X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), UV-Visible Spectroscopy (UV-Vis), Photoluminescence (PL), and Raman Spectroscopy (FT-R) studies. The influence of thiourea on the structural and optical properties of ZnS films was discussed in detail. The X-ray diffraction patterns confirmed the rhombohedral structure of ZnS thin films. AFM measurements indicated the nano carpet-like surface morphology variation in film with influence of thiourea. The optical absorption studies in the wavelength range of 200-800 nm showed that the band gap energy of ZnS has decreased from 3.69-3.36 eV, as thiourea varied from 0.2-0.8 M. The PL spectra divulged a shift near band edge emission around 360 nm, when thiourea concentration was increased. The Stokes shift calculations from PL emission spectra supported the relative intensities estimated from PL energy band spectra and showed a dependable repeatability for different molar concentrations. The Zn-S complexes were identified in the Raman spectra and the Raman spectral shift for 0.6 M composition of thiourea, which was found to be appreciable for ZnS thin films. The characterization studies clearly exposed the effect of thiourea onto the chemically deposited ZnS thin films.
