Chemical Precipitation Synthesis of Ferric Chloride Doped Zinc Sulphide Nanoparticles and Their Characterization Studies

摘要

Nanoparticles of Ferric Chloride doped ZnS has been synthesized by simplechemical precipitation method and characterized by XRD, SEM, UV-Vis analysis,Differential Thermal Analysis, Thermo Gravimetric Analysis and DifferentialScanning Calorimetry. XRD patterns of the samples reveal particle size,specific surface area and the formation of cubic structure. The SEM images showthat the cauliflower likes structure. Optical band gap values have beenobtained from UV-Vis absorption spectra. It has also been found that energyband gap (Eg) increases with the increase in molar concentration of reactantsolution. Thermal analysis measurement of the prepared sample shows that thethermal stability of pure ZnS is decreased due to increase in Ferric Chlorideconcentration. Undoped ZnS is more thermal stable when compared to FeCl3 dopedZnS.
