“…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.

“…N. Kamoun Allouche et al studied ZnS multilayer films and found more than 70 % transmission in the wavelengths above 350 nm and an optical band gap of about 3.76 eV (Allouche et al, 2010). Optical properties of nanocrystalline Ni doped ZnS thin films were studied by R Sahraei et al (Sahraei and Darafarin, 2014 ). Optical transmittance of 75 % in the visible range and band gap up to 3.66 eV was observed in Al doped ZnS thin films at different Al concentration (Nagamani et al,, 2012).…”

Thin films of ZnS and Cr doped ZnS have been deposited on glass substrates by chemical bath deposition (CBD) method taking ammonia as complexing agent. The pH of the solution was maintained at 8−9 at a temperature of 70 o C. Characterization of the ZnS and Cr-doped ZnS films were carried out using X-ray diffraction (XRD), X-ray Fluorescence Spectrograph (XRFS) and Atomic force microscopy (AFM). Structural properties and optical absorption has been observed for both doped and undoped films. Parameters like crystallite size, lattice constant, microstrain, dislocation density; and optical constants such as extinction coefficient, absorption coefficient for both types of films were measured from XRD and absorbance spectra respectively. Studies show that there is an increase of crystallite size and good optical properties in visible region from 420 nm in Cr-doped ZnS thin film.
