Synthesis and characterization of MWCNT/CdS nanocomposite

In this work we report the synthesis and characterization of hybrid nanostructures of multiwall carbon nanotubes (MWCNT) and cadmium sulphide (CdS) nanoparticles. In a solution of thioacetamide and cadmium sulphide, purified MWCNT are added to prepare the CNT/CdS hetrostructure. XRD diagrams, SEM images, and also photoluminescence spectra of the prepared samples are analyzed. SEM images show the CdS nanoparticles of 17nm size coated on the CNTs. Visible photoluminescence with peaks at 435 nm and 535 nm, obtained from the prepared CNT/CdS, is discussed. The synthesis technique can be simply extended to other luminescent dopants, and the possibility of making optoelectronic devises based on the CNTs is confirmed by this method
