A. Turkovic et al., Small angle scattering of synchrotron radiation on nanosized CeO2 and CeO2-SnO2 thin films obtained by sol-gel dip-coating method, NANOSTR MAT, 11(7), 1999, pp. 909-915
Nanosized CeO2, and CeO2-SnO2, 100-500 nm thick, films on glass substrate w
ere prepared using sol-gel dip-coating method procedure. The average grain
size <R>, obtained by SAXS (small-angle X-ray scattering), varied with the
number of dips for the CeO2-SnO2 samples. For the CeO2 films, obtained by d
ipping it 8 times, <R> increased compared to CeO2-SnO2 films, which were ob
tained by the same number of dips, from 4.4 to 5.3 nm. Specific surface are
as of both these films were also determined and varied from 0.18 x 10(7) to
0.51 x 10(7) cm(-1). SAXS measurements also revealed the layered structure
of CeO2 and CeO2-SnO2 firms. (C) 1999 Acta Metallurgica Inc.
