“…The water-soluble CdS NCs were prepared in an aqueous solution using thiols as stabilizing agents, which was first reported by Weller's group [4]. Up to now, many methods for preparing CdS NCs in an aqueous solution have been developed [5][6][7][8]. Of them, sodium sulfide [9], thiourea [10] and thioacetamide [11] were often used as sulfur sources.…”

ABSTRACT ABSTRACT. A novel method has been developed for the synthesis of CdS nanocrystals (NCs) using thioglycolic acid (TGA) as a sulfur source and stabilizer with the presence of hydrogen peroxide in an aqueous medium. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy. The results indicate that the product was of zincblend crystal structure in a sphere-like shape. The room-temperature luminescence spectra revealed that the emission peak of CdS NCs prepared in relatively short refluxing times (10-120 min) could be tuned from 518 nm to 610 nm, and the photoluminescence quantum yield of the as-prepared CdS NCs could reach as high as 12.6%. In addition, the mechanism of the CdS nanocrystals formation was preliminarily discussed. KEY WORDS KEY WORDS KEY WORDS
