Decoration of CdS nanoparticles on MWCNT's by simple solution chemistry

► The decoration of CdS nanoparticles over MWCNTs was done at low temperature (70 °C). ► Simple and inexpensive route namely chemical bath deposition method was employed. ► The CdS nanoparticles coated on MWCNTs clearly demonstrates size quantization. ► The process opens way to coat variety of inorganic semiconducting nanoparticles.
