Novel nanorod-assembling hollow nanowires of cadmium sulfide/DBTU (N,N'-dibutylthiourea) nanocomposite were synthesized by reacting CdCl{sub 2} with in situ produced H{sub 2}S from reaction of butylamine and carbon disulfide at molar ratio 3:3 of CS{sub 2}:BuNH{sub 2} at 50 {sup o}C. This product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SEAD), energy dispersive X-ray spectroscopy (EDAX), thermogravimetric (TG), Fourier transform infrared (FTIR) and UV-vis absorption spectra. A plausible mechanism that the extending DBTU molecules in solvent of CS{sub 2} induce the formation of CdS/DBTU nanorods by coordinating with the formed CdS particles, and construct these nanorods to hollow nanowires via molecular interactions is proposed and discussed on the basis of experimental results. Photoluminescence (PL) of CdS/DBTU nanocomposite exhibits increasing emission intensity largely.
