Cadmium Sulphide, Chemical Precipitation, XRD, TGA, DSCAbstract
Undoped Cadmium sulphide and doped cadmium sulphide nanomaterials with copper and silver are effectively synthesized using ethylene glycol as a capping agent by the chemical precipitation process. Scanning electron microscopy and x-ray diffraction studied the composition and crystalline structure of materials. These techniques have estimated the average particle size of such nanomaterials to be between 4-8 nm. Energy Analysis Dispersive X-Ray reveals the components present in these materials. Using UV-visible absorption spectrums, the nanoparticles were calculated in the band gap, resulting in significantly blue values being moved from the large Cadmium Sulphide Band Gap values. The thermal properties of the nanomaterials were analysed by Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC).
