Abstract

Oleic acid (OA)-capped CdS nanoparticles (NPs) have been successfully synthesized via the direct reaction of Cd(CH2COO)2·2H2O with S powder in OA solvent at 230 °C under nitrogen flow, which was a kind of clean and air-stable solvent. The morphologies and structures of the as-synthesized CdS NPs are examined by transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), X-ray diffractometer (XRD), and Fourier transform infrared (FTIR) spectroscopy, and the typical Ostwald ripening growth mechanism is concluded. Moreover, the collected ultraviolet–visible (UV–vis) absorption spectroscopy and photoluminescence (PL) spectroscopy demonstrate good optical properties of CdS NPs.

► One-pot method, which is suitable for large-scale preparation was developed to prepare CdS NPs. ► Oleic acid is first used as the single coordinating solvent and stabilizer to synthesize CdS NPs. ► UV–vis and PL spectroscopies demonstrate good optical properties of our CdS NPs.
