This study aimed to determine the effect of Al-doping on the physical properties of ZnS thin films. The pulsed-laser deposition technique was used to prepare ZnS and Al-doped ZnS (AZS) thin films on soda-lime glass slides. The Al concentration of 0–6% was used. Further, XRD spectroscopy was employed to confirm the structures of the ZnS and AZS films, following which the values of parameters such as crystal plane spacing, crystallite grain size, microstrain, and dislocation density were calculated. Regarding ZnS, the result showed a broad pattern corresponding to the (111) plane of ZnS. There was a variation of 0.313–0.316 nm in the d-spacing, which decreased as the concentration of Al in the ZnS films increased. The crystallite size was found to be 0.80–671.24 nm. Notably, the crystallite size was affected by the Al concentration. The change in the a aluminum content from 0 to 8% make change in thee strain increase from 0.00046 to 0.0031. Also, as the Al-doping increased, the dislocation-density reduced from 1.54 to 0.00000221 mg.cm-3 . The values obtained in this work were consistent with published standards.

Zinc Sulfide (ZnS) get important attention as a semiconductor photocatalyst among other transition metal sulfides due to its fascinating and extraordinary properties. Here ZnS nanoparticles are synthesized by hydrothermal method using zinc acetate and sodium sulfide as precursors. The structural properties of ZnS was studied by using X‐Ray Diffraction technique (XRD).Exact fitting and crystal information of the sample was obtained from Rietveld refinement with Crystallographic Open Database (COD). It shows that ZnS follows cubic structure without any impurity peaks. Crystallite size and lattice strain values are calculated by using Williamson‐Hall (W−H) Plot method. As temperature increases, the particle size also going to increases due to atomic diffusion phenomena. Tauc plot indicates that the bandgap values decreases with increasing temperature. Accurate determination of bandgap values was analyzed by Boltzmann fitting using sigmoid function. Chemical states of elements were obtained with X‐ray Photoelectron Spectroscopy (XPS).Surface morphology and elemental analysis of ZnS nanoparticles was determined from Field Emission Scanning Electron Spectroscopy (FESEM) and Energy Dispersive spectroscopy (EDS). Then the photocatalytic dye degradation efficiency of synthesized particles for Malachite Green (MG) dye was evaluated. From the studies it was found that ZnS is an efficient photocatalyst and it can be used as a perfect future material to avoid the water pollution.

“…The I-V study was done on two-electrode system. I-V curve for ZnS material synthesized by Choudapur.et.al shows a current response of 0.05mA for -1 Volt to 1 Volt [17] whereas studies performed by us shows a good current response of 75mA for -1 Volt to 1Volt as depicted in figure-6. This made the green synthesized ZnS a novel material due to its current response against given voltage.…”

ZnS quantum dots were synthesized using green synthesis route which are cost effective and eco-friendly. X-ray diffraction study revealed the formation of single phase ZnS. Crystallite size and strain in the as synthesized material were calculated through Williamson-Hall and Size-Strain plot. UV-Vis spectroscopy investigations revealed the absorption region and optical band gap for the ZnS with refractive index analysis. Microstructural analysis of material was done using high resolution transmission electron microscope (HRTEM) which confirms the presence of quantum dots. Selected area electron diffraction pattern (SAEDP) of the corresponding area revealed the polycrystalline nature of as synthesized ZnS with fine crystallites oriented along (111) and (022) planes. Results of analysis of lattice fringe spacing’s of fine crystallites are found to be in good agreement with SAEDP data. Elemental compositional analysis was carried by using EDS as an attachment of TEM which showed the presence of Zinc and Sulphur only. Nyquist plot reported Warburg impedance which suggests the material for solar cell applications.
