摘要

Metal oxide clusters are employed in studies to help understand an important, specific, type of surface chemical problem: the contamination of soft x-ray mirrors by carbon deposits. Herein we report nanocluster chemistry studies that are relevant to the use of silicon oxide and titanium oxide capping layers. Systems involving Si_mO_n, and Ti_mO_n metal oxide nanoclusters are generated in a pulsed supersonic expansion/ablation source and passed through a reactor containing any reactant desired. The reaction products of these gas phase clusters are ionized using single photon ionization from a desk-top sized 46.9 nm Ne-like Ar laser providing the advantage of little or no fragmentation of desired nanoclusters. The ionized products are analyzed by a time of flight mass spectrometer and experimental results supply useful information related to condensed phase soft x-ray optical surfaces. The results illustrate the great potential of the use of very compact soft x-ray lasers in photochemistry and photophysics studies.
