Chemistry Building, Room 400
Physical Seminar

A laser vaporization flow reactor (LVFR) apparatus has been developed for the synthesis of ligand-coated metal oxide nanomaterials. This method produces gas phase clusters followed by ligand coating and collection in a cold trap. Upon warming of the material, a solution is obtained for characterization by a variety of techniques including: mass spectrometry, electronic spectroscopy, infrared and Raman spectroscopy, and electron microscopy. Synthesis and characterization of ultra-small chromium oxide nanoclusters and molybdenum oxide nanorods will be discussed.
