Solvothermal Synthesis and Characterization of Surfactant-Modified CdS Microspheres

摘要

CdS crystals with spherical morphology have been prepared by a solvothermal method using a self-made novel block-like imidazoline-gemini surfactant quaternary ammonium salt of di (2-undecyl-1-formyl aminoethyl thiourea imidazoline) hexanediamine (SUDEIHDI) as the shape-controlling agent. The obtained CdS products are characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), infrared ray spectroscopy (IR), UV-vis absorption spectroscopy, and x-ray diffraction (XRD), respectively. In addition, the formation mechanism for the CdS sphere was also discussed.
