•CuInS2 nanoparticles are grown on MWCNTs by a solvothermal approach.•Reaction conditions greatly influence the resulting MWCNT–CuInS2 hybrids.•The hybrid samples have been extensively characterized.•The hybrids show better optical limiting performance than MWCNTs.
CuInS2 nanoparticles (NPs) have been decorated on the sidewalls of multiwalled carbon nanotubes (MWCNTs) by a solvothermal approach using copper diethyldithiocarbamate and indium diethyldithiocarbamate as precursors. The resulting MWCNT–CuInS2 hybrid samples have been extensively characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform IR spectra, ultraviolet–visible–near infrared spectra and X-ray photoelectron spectroscopy. The precursor concentration, reaction temperature and reaction time have a great influence on the size and morphology of the formed CuInS2 NPs. The open-aperture z-scan technique has been used to study the nonlinear optical properties of two typical MWCNT–CuInS2 samples, which show better optical limiting performance than purified MWCNTs.
