E. Zhang X. D. Pan H. Zhu S. Z. Li G. Y. Xu X. B. Zhang A. L. Ying Z. W. Tong Received 6 May 2008 Accepted 11 July 2008 Published online 9 August 2008 to the authors 2008 Abstract Cd OH 2 nanobelts have been synthesized in high yield by a convenient polyol method for the first time. xRd XPS FESEM and TeM were used to characterize the product which revealed that the product consisted of belt-like crystals about 40 nm in thickness and length up to several hundreds of micrometers. Studies found that the viscosity of the solvent has important influence on the morphology of the final products. The optical absorption spectrum indicates that the Cd OH 2 nanobelts have a direct band gap of eV. Keywords Crystal morphology Nanobelt Viscosity Hydrothermal Introduction One-dimensional 1D nanostructures such as wires rods belts and tubes whose lateral dimensions fall anywhere in the range of 1-100 nm have become the focus of intensive research owing to their unique applications in mesoscopic physics and fabrication of nanoscale devices 1-6 . Among one-dimensional 1D nanostructures nanobelts or nanoribbons a relatively new family of 1D nanostructures with a rectangular cross section have received increasing attention D. E. Zhang X. D.
