Abstract

Nanocrystalline AlySn1−yO2−y/2 (y = 0.57, 0.4) was prepared by a co-precipitation method and subsequent calcination at temperatures of up to 650 °C. Transmission electron microscopy and X-ray diffraction reveal crystallite sizes of about 2 nm and a crystal structure equivalent to that of pure SnO2 cassiterite. The local structure was investigated by 27Al and 119Sn NMR as well as by Sn Mössbauer spectroscopy. The results show the formation of a solid solution with a random distribution of Al and Sn on the cation sites and a random distribution of oxygen vacancies on the anion sites.
