Si-based porous alumina is prepared by anodization of aluminum film grown on the silicon substrate and this structure c ould act as a template for preparation of Si-based nano-materials.Using this template,Si-based CdS nanowires are fabricated by non-aqueous electrochemical deposition method.The prepared sample is characterized by X-ray diffraction( XRD).Its morphology is observed by both transmission electron microscope(TEM )and atomic force microscope(AFM).Meanwhile,CdS nanowires deposited in Si- based porous alumina film present good light-emitting properties,which is expe cted to be used as Si-based nanoscaled light source.
NiO nanoparticles are prepared via thermal decomposition of nickel acetate coated by β-CD, and Characterized by using X-ray diffraction (XRD), transmission electron microscopy (TEM). Thermo-gravimetric (TG) analysis and electro spray mass spectrum (ESI-MS) are performed to investigate the thermal decomposition process and the possible formation mechanism of obtaining good morphology NiO nanoparticles by this method. Further, different CDs are used to prepare the precursors of inclusion complexes, and there are little affect of CD′s type on the NiO nanoparticles.
