摘要：

Decomposition of the organometallic precursor [Sn(NMe2)(2)](2) in a controlled water/anisol mixture leads to the formation of monodisperse nanocomposite particles of Sn/SnOx. Full oxidation of the particles into SnO2 occurs at 600 degrees C without size or morphology change. These particles can be deposited onto silicon nitride covered microelectronic platforms and used as sensitive layers of gas sensors. Doping of the sensors with palladium can be achieved either by co-decomposition of organometallic precursors (doping in volume) or by deposition of palladium on preformed SnO2 nanoparticles (doping in surface). The doped sensors display an unusually high sensitivity for CO sensing. (C) 2000 Elsevier Science B.V. All rights reserved.
