摘要：
Flame spray pyrolysis (FSP) has been used to synthesize tin oxide nanoparticles from the ethylhexanoate precursor in ethanol. The particles were highly crystalline having a primary particle and crystallite size of 17 nm. The single crystalline particles were only slightly aggregated and directly used for thick film sensor deposition by drop coating. The flame made SnO2 nanoparticles showed high and fast response to both reducing (propanal) and oxidizing (NO2) gases. (C) 2003 Elsevier B.V. All rights reserved.
