Preparation and characterization of Sb۶O۱۳ nanocrystals by hydrothermal method

A simple hydrothermal method has been developed for synthesizing of Sb۶O۱۳ nanocrystals at a high yield at ۱۸۰°C that is a new method for preparing these nanocrystals. Thoroughly mixtures of antimony oxide (Sb۲O۳) and cerium oxide (CeO۲) used as a starting material. Antimony oxide to cerium oxide molar ratio in different experiments was either ۱:۱, ۱:۲, ۱:۳ and ۱:۴. Cell parameters were determined by CELEREF software (۱۰.۲۹۶۳, ۱۰.۲۹۵۱, ۱۰.۲۹۲۰, ۱۰.۲۹۹۷ for ۱:۱, ۱:۲, ۱:۳, ۱:۴, molar ratios respectively). In all of ratios, XRD result was similar. FT-IR, XRD, UV, Flouresance and SEM were used to analysis the structure characteristics of Sb۶۰۱۳ nanocrystals. Band gap for Sb۶۰۱۳ nanocrystals is ۲ev.
