Abstract
Tin oxide nanoparticles were produced with tin in a variety of oxidation states. In particular, nanoparticles of single phase, crystalline SnO.sub.2 were produced. Preferred tin oxide nanoparticles have an average diameter from about 5 nm to about 100 nm with an extremely narrow distribution of particle diameters. The tin oxide nanoparticles can be produced in significant quantities using a laser pyrolysis apparatus. Nanoparticles produced by laser pyrolysis can be subjected to further processing to change the properties of the particles without destroying the nanoscale size of the particles. The nanoscale tin oxide particles are useful for the production of transparent electrodes for use in flat panel displays.
