摘要：

Cadmium sulfide/organic nanocomposites, which were based on long nanowires, were synthesized by a simple reaction between cadmium nitrate 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 (SAED), Fourier transform infrared (FTIR) spectra, and thermogravimetric analysis (TG). The CdS/organic nanocomposites was decomposed into pure wurtzite CdS nanorods through hydrothermal treatment at 190 degrees C. Photoluminescence (PL) spectra were used to study the optical properties of CdS/organic composite and pure CdS. It is found that the emission maximum of the CdS/TGA nanocomposite is significantly blue-shifted, and the intensity is highly enhanced as compared to the luminescence spectrum of the bare CdS nanorods.
