Nanoparticles and Nanocomposite Thin Films Prepared by Gas Aggregation Source — •Oleksandr Polonskyi, Thomas Strunskus, and Franz Faupel — Chair for Multicomponent Materials, Faculty of Engineering, Christian-Albrechts University at Kiel, Kaiserstr. 2, 24143 Kiel, Germany

Nanocomposite thin films consisting of metal nanoparticles (NPs) in a dielectric organic or ceramic matrix have unique functional properties with numbers of applications. The metallic nanoparticles typically form via a self-organization during co-deposition of the metallic and matrix components. Various methods such as sputtering, evaporation, and plasma polymerization have been applied for the deposition of the matrix component, while the metallic component has mostly been sputter deposited. However, recently gas aggregation nanoparticle sources have attracted high interest in order to obtain independent control of filling factor and size distribution of the embedded metallic nanoparticles. In the present talk, the details about formation of nanoparticles and nanocomposites by means of gas aggregation method will be discussed. In addition, we report on the <<in-flight>> treatment of metallic nanoparticles, generated by gas aggregation method for novel nanostructure formation. Here, in particular, the attention will be paid to optical composites and silver containing biocompatible antibacterial coatings with tailored release rate.
