Antimony-doped tin oxide nanocrystals: Synthesis and solubility behavior in organic solvents

Abstract

This work focuses on the nonaqueous synthesis of antimony-doped tin oxide nanocrystals in the size range of 2 6 nm and the investigation of their solubility in organic solvents (CHCI3 and THF) in the presence of amphiphilic molecules (oleic acid and oleylamine). To unravel the underlying processes, a set of molecular dynamics simulations is performed involving the compatibility of oleic acid and oleylamine in mixtures with both CHCl 3 and THF. The results show that the method is useful for obtaining the desired oxide, and that the interaction between amphiphilic molecules and solvents can be predicted by molecular dynamics simulations with very good qualitative agreement. © 2009 Wiley-VCH Verlag GmbH&Co.
