摘要：

Sin-doped cerium dioxide (SDC) with fee structure was formed using a gas-liquid chemical co-precipitation process at room temperature. Morphology and structure of the as-prepared samples were characterized using TG, XRD, TEM, HRTEM and SAED techniques. Under our specific experimental conditions, two kinds of ID nano-structures SDC have been mainly obtained. SDC nanowires are 0.3-1.2 mu m in lengths and 5-20 nm in diameters. SDC nanotubes have outer diameters in 10-40 nm with lengths up to 2 mu m. The as-prepared SDC shows very strong UV absorption ability and the maximum absorption peak redshifts compared with that of SDC nanoparticles. (C) 2007 Elsevier Ltd. All rights reserved.
