Abstract

Cd(OH)2nanobelts 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)2nanobelts have a direct band gap of 4.45 eV.

Highlights

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 [1,2,3,4,5,6]

Summary

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 [1,2,3,4,5,6]. Cd(OH), is a wide band gap semiconductor [25] with a wide range of possible applications including solar cells, photo transistors and diodes, transparent electrodes, sensors, etc. Up to now, to our best knowledge, the synthesis of Cd(OH) nanobelts by hydrothermal process has not been reported. We report the preparation of cadmium hydroxide nanobelts by the conventional polyol assisted hydrothermal process
