Hydrothermal Methods

Ag @ C core–shell structures were prepared using hydrothermal methods by AgNO 3 reduction with ascorbic acid in the presence of polyacrylamide (PAM). Temperature plays a key role in the formation of the core–shell structures. The roles of reactants, surfactant concentrations and reaction time on the morphologies of core–shell nanoparticles were investigated in detail. This synthetic method is one-pot synthesis, which is fast, high-yield and environmental-friendly for fabrication of Ag @ C core–shell structures. The surface properties of core–shell Ag @ C nanoparticles were characterized by Raman spectroscopy.

Core Shell Nanoparticles

Core-shell nanomaterials based on CdSe as the core and ZnO as the shell were prepared using an aqueous route involving the use of Cd salt and NaBH4in reaction with Se to generate CdSe in the presence of thioglycerol (TG) as a stabilizer. ZnO has been prepared at pH 12 using stronger base such as NaOH at lower concentration and by varying amounts of Zn2+ions ranging from 2.5, 5, 25 mL, and 50 mL to prepare core-shell nanomaterials. The absorption and emission spectral features are dominated by CdSe nanoparticles with typical shift in the emission maxima red-shifted in relation to the band edges. There is an observable change in the band edge from the core as the amount of ZnO is increased. The TEM features showed the formation of the core-shell from the volume of 5 mL which is indicated by the thin layer of shell on the surface of the CdSe core.
