Synthesis and Characterization of a Fe~(3+) Doped SnO2 Nanopowder

摘要

Tin dioxide is an-type wide band gap semiconductor. Transition metal doped tin dioxide materials are widely investigated due to their potential applications as diluted magnetic semiconductors. We describe for the first time the use of a 1:1 isopropanol + glycerin mixture in the sol-gel synthesis of a Fe~(3+) doped tin dioxide nanopowder. Through this method, 5 nm crystallites are obtained. The samples structural characterization was carried out with FT-IR, XRD and XPS analysis.
