| Abstract: | Novel cadmium sulfide/organic composite hollow spheres composed of sword-like nanorods were synthesized via a simple reaction between cadmium salts and thioglycolic acid (TGA) at room temperature. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SEAD) and Fourier transform infrared (FT-IR) spectra. Thermal stability of the organic composite was investigated. CdS/organic composite would decompose into pure wurtzite CdS through hydrothermal treatment. Effect of the cadmium source on the formation of the CdS/organic composite was investigated. Photoluminescence (PL) was used to study the optical properties of CdS/organic composite and pure CdS. |
