Fabrication and optical characterization of cadmium sulfide needles using nuclear track membrane

Cadmium sulfide needles with a diameter of 0.2 mu m have been fabricated in nuclear track polyethylene-terephthalate (PET) membrane by electrochemically depositing from organic solvent dimethylsulfoxide (DMSO) containing CdCl2 and elemental sulfur at the temperature 110 degrees C. The characterization of the sample of CdS needles was studied by scanning electron microscope, X-ray diffraction, absorption and photoluminescence spectra. The optical experiments show that in the sample of CdS needles there is an absorption peak that could be assigned to the interface states of the CdS needles.
