摘要：

SnO2 nanoparticles were prepared by citric acid assisted hydrothermal process and its microstructure and optoelectronic properties had been investigated. Based on XRD, TEM and FT-IR analyses, the SnO2 crystallites with the tetragonal rutile structure were directly formed. The crystalline grain size of SnO2 was 6.0nm and its specific surface area reached 206m(2)/g. The room temperature photoluminescence proved that it had a blue emission, which increased remarkably after SnO2 calcined at 800 degrees C. (C) 2008 Elsevier B.V. All rights reserved.
