Abstract:

Molecular beam experiments employing laser vaporization, time-of-flight mass spectrometry and laser photodissociation were employed to study a variety of metal compounds nanoclusters to evaluate their potential for new materials. Mixed atomic clusters of copper, silver and gold with carbon or silicon were studied as well as several transition metal oxide clusters. New laser techniques were developed and employed to make metal and metal oxide complexes with polycyclic aromatic hydrocarbon species. In a combination of laser vaporization methods with inorganic synthetic methodology, ligand-coated metal and metal oxide clusters for the early transition metals titanium and vanadium were synthesized and collected in macroscopic amounts for the first time. These oxides are sub-nanometer in size, representing some of the smallest particles ever isolated.
