Synthesis, Structural and Morphological Studies of CdS Nanopowder

Santhosh Kumar N, Govinda D and Thirumala Rao G

Hexagonal wurtzite structured CdS nanopowder was synthesized by using chemical precipitation method. Various spectroscopic technics were used for the characterization of the prepared sample. X-ray diffraction pattern shows the high intense crystalline peaks and the average crystallite size is found to be 19 nm. SEM micrographs reveal the non-uniformly distributed spherical shaped structures. EDS analysis confirms the stoichiometric composition and presence of target elements. FT-IR spectrum exhibited a metal sulfide band at 615 cm–1 and other functional groups.
