One-dimensional structures of Bi2O3 synthesized via metalorganic chemical vapor deposition process

We have demonstrated the synthesis of one-dimensional (1D) structures of bismuth oxide (Bi2O3) by a reaction of a trimethylbismuth (TMBi) and oxygen (O-2) mixture at 450 degrees C. Scanning electron microscopy showed that the product consisted of ID materials with width or diameters less than I mu m and lengths up to several tens of micrometers. The X-ray energy dispersive spectroscopy revealed that the materials contained elements of Bi and O. The results of X-ray diffraction and selected area electron diffraction pattern indicated that the obtained Bi2O3 were crystalline with monoclinic structure. (c) 2005 Elsevier Ltd.
