Nucleation, growth and spectroscopy of ceramic and metallic clusters in laser-driven synthesis

Objective



Ultra-fine metallic and ceramic particles are promising substances for chemical catalysts, magnetic materials and sensors. Moreover, materials made from these particles have been considered for a large variety of other applications because of their unique chemical, thermal and mechanical properties, such as hardness, high-temperature strength and resistance to thermal shock, oxidation, and corrosion.

Laser-driven gas phase reaction is one of the most promising approaches to the production of ultra-fine clusters. Successful application of this technique relies on a detailed understanding of the underlying physical processes in order to control the laser-driven reactions and the morphological properties of the powders produced.

The objective of this present project is an investigation of the nucleation and growth stages along with the spectral structure of clusters obtained in the laser-driven powder-synthesis reactions. This will be carried out with the help of the most sensitive modern diagnostics, such as laser-induced fluorescence, mass-spectrometric analysis and detection of laser light scattered by clusters.
