微波固相反应制备CdS纳米粒子

摘要

CdS nanoparticles with different sizes have been successfully synthesized by microwave-assisted solid state reaction between Cd(CH3COO)2·2H2O and Na2S·9H2O at the presence of suffactant PEG400. The process of heating has influence on the crystallinity of CdS. The products were characterized by XRD, SEM, TEM, and the formation mechanism of CdS nanoparticles has also been discussed.
