Synthesis and Characterization of Glucuronic Acid Capped CdO and CdS Nanoparticles

摘要

Cadmium oxide and cadmium sulphide nanoparlicles have been prepared with variety of stabilizers for different purposes and glucuronic acid is used for capping CdS and CdS nanoparticles. These nanoparticles were prepared by using cadmium acetate with thioacetamide for CdS and cadmium chloride and the strong base for CdO nanoparticles. The as obtained CdO and CdS nanoparticles were characterized by a combination of microscopy and spectroscopic techniques for their morphology, size and crystallinity. The glucuronic acid-capped CdS and CdO nanoparticles showed blue shifts in their absorption band edges and with emission maxima red shifted from the band edge. The particles were obtained with good crystallinity and spherical in shape with relatively narrow size distribution.
