Abstract

SnO₂ nanocrystals with an average particle size of 3.5 nm are obtained by heating the mixture of hydrous SnO₂ nanoparticles and SrCO₃ particles. SrCO₃ can be removed from the product by washing with diluted HNO₃ acid. A series of SnO₂ nanocrystal samples with different particle size are prepared by heating at different temperature. All the samples obtained are characterized by XPS and Raman spectra. XPS result shows that the binding energy of Sn3d_5/2 decreases as the particle size increases. There is a surface-related Raman peak observed, which increases in intensity when the SnO₂ particles size decreases. The size-related change of the surface structure is responsible for the properties of nanocrystals.
