Multifunctional nanoparticles have attracted significant interest for their multifunctional applications. Described herein is the building of a new hybrid nanocomposite particle, conjugating tungsten disulfide (WS 2 ) nanotubes (NTs) to fluorescent carbon dots (C‐dots). Hybrid WS 2 ‐C‐dots hyb‐NTs nanomaterials are prepared by a hydrothermal reaction of PEDOT Ac ‐WS 2 NTs, where the PEDOT Ac (poly 2,3‐dihydrothieno[3,4‐b][1,4]dioxine‐2‐carboxylic acid) polymer serves as the C‐dots precursor. The physical and chemical properties of the as‐synthesized WS 2 ‐C‐dots hyb‐NTs are determined by X‐ray powder diffraction (XRD), transmission electron microscopy (TEM), CHNSO analysis, and fluorescence, Raman, and UV–vis absorption spectroscopy. The WS 2 ‐C‐dots hyb‐NTs are shown to be very stable at normal room temperature and pressure and could be useful for multicolor cell imaging and targeted cell killing.
