Mophological study on zinc sulfide (ZnS) synthesized by a solid state reaction on the outermost shells of multiwalled nanotubes (MWNT) is presented. It was found that ZnS coats the surface of CNTs in the forms of ultrathin films, quantum dots, and nanorods. ZnS nanorods were grown on the surface of MWNTs without the presence of catalyst suggesting the vapor-liquid-solid (VLS) mechanism is not applicable for the here shown growth process. The average diameter of nanorods on MWNTs is about 140 nm and the length is around 250 nm. @FootnoteText@ Zinc Sulfide Coating on Carbon Nanotubes.
