Hydrothermal synthesis of antimony oxychloride and oxide nanocrystals: Sb4O5Cl2, Sb8O11Cl2, and Sb2O3

摘要

We described herein a facile solution-phase route to three nanocrystals of antimony oxychlorides and oxides (Sb4O5Cl2, Sb8O11Cl2, and Sb2O3),whose morphologies and phases were varied with the pH value of a reaction mixture or composition of a mixed solvent. In particular, the solvent composition controlled the selective preparation of cubic Sb2O3 (senarmontite) and orthorhombic Sb2O3 (valentinite). Both Cubic and orthorhombic Sb2O3 samples exhibited strong emission properties. (C) 2008 Elsevier Inc. All rights reserved.
