| dc.description.abstract | An environmentally friendly synthetic route has been used to synthesize cadmium selenide and zinc selenide nanoparticles. Both aqueous and organically soluble selenide based nanoparticles have been synthesized via mild conditions. The synthesis involved the reduction of selenium powder to produce selenium ions. The complete reduction of selenium is followed by the addition of a metal source MX (M = Cd or Zn and X = Cl or CO). Biocompatible passivating agents such as cysteine or triethanolamine (TEA) induced the solubility of the nanoparticles in water, while the solubility of the nanoparticles in the organic solvents was facilitated by hexadecylamine (HDA). The evidence for the formation of the nanoparticles with a desired quality was confirmed by using different techniques such as UV-Vis absorption spectroscopy, photoluminescence spectroscopy (PL), X-ray diffraction (XRD), transmission electron microscopy (TEM) and infrared spectroscopy (FT-IR). | en_US |
