Synthesis of CdS nanoparticles by a novel and simple one-step, solid-state reaction in the presence of a nonionic surfactant

摘要

A novel and simple one-step, solid-state reaction in the presence of a nonionic surfactant, C_(18)H_(37)O(CH_2CH_2O)_(10)H (abbreviated as C_(18)EO_(10)), has been developed to synthesize uniform cubic-phase β-CdS nanoparticles with an average diameter of ca. 5 nm. The CdS nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), UV―VIS optical absorption spectrum and X-ray photoelectron spectrum (XPS). The roles of nonionic surfactant, C_(18)EO_(10), in the formation of CdS nanoparticles were discussed in detail.
