Chemical preparation of core - shell nanoparticles

Abstract

Nanoparticles obtained during layer-by-layer chemical deposition have been obtained. The particles diameter varied between 5 nm and 9 nm and can be tuned by changing molarity of the synthesis ingredients. The intention was the creation of copper or iron oxide layer during the process. Layer composition were changed using Cu rich or Fe rich ingredients. Magnetic properties of the particles strongly depend on the composition of covered material, indicating for their core-shell structure
