Paper Abstract

A pulsed XeCl laser was used to ablate copper and aluminum samples in vacuum or in ambient atmosphere. The space- and time-resolved emission spectroscopy of the ablated plasma plume was studied. The structure and composition of the synthesized products, copper oxide, alumina and aluminum nitride ultrafine powders were analyzed by x-ray diffraction and x-ray induced photoelectron spectroscopy. The morphology and size distribution were investigated using a transmission electron microscope and particle size analyzer. Preliminary results are presented and discussed.
