油酸钠为稳定剂合成CdS(CdSe)纳米粒子及表征
Synthesis and characterization of CdS (CdSe) nanoparticles with sodium oleate as stabilizer
摘要
Abstract
In order to solve such problems as difficult recycling,high cost and hard industrialization realization for the used organic solvent in the preparation process of CdS (CdSe) semiconductor nanoparticles,the CdS and CdSe nanoparticles were prepared by taking the sodium oleate as stabilizer,ethanol as solvent as well as cadmium acetate and thiourea (or NaHSe) as precursors,respectively.The optical properties,crystalline structures,morphologies and dimensions for both CdS and CdSe nanoparticles were characterized with such methods as UV-VIS absorption spectrum,fluorescence spectrum,wide angle x-ray diffraction (WAXD)and transimmision electron spectroscopy (TEM).The results show that with taking the sodium oleate as stabilizer and ethanol as solvent,the CdS and CdSe nanoparticles with homogeneous dimension distribution can be obtained in moderate reaction condition through controlling certain precursor concentration,reaction temperature and reaction time.Therefore,a new way for the synthesis of CdS and CdSe seimconductor nanoparticles in environment-friendly condition can be provided.关键词
