Synthesis and investigation of cobalt containing nanoparticles morphology
The aim of this work is to develop methods of synthesis of stable monodisperse cobalt sol by the method of chemical reduction and obtain cobalt thin films on a silicon substrate, investigate their morphology and geometrical characteristics. Cobalt acetate was used as a precursor in this study, ascor...

The resulting sol was studied by the method of photon correlation spectroscopy. Analysis of the data of the photon correlation spectroscopy revealed the presence of two fractions in a sample with an average hydrodynamic radius of the smaller fraction of about 3.9 nm and the larger one-278 nm. Thin cobalt films were obtained by the method of drying the sol and method of rotating substrate coating.
