Abstract

Selenium nanowires have been grown by chemical method. The effect of annealing on the properties of the prepared selenium nanowires has been studied. The X-ray diffraction studies indicated the formation of selenium with trigonal phase, and no secondary phase was observed. The composition analysis results show that selenium is present in the sample. HRTEM images reveal that selenium nanowires have diameter ranging from 30–50 nm and length of 1-2 μm. The diameter and length of nanowires have been found to increase with increase in annealing temperature.

Summary

Introduction

One-dimensional (1D) nanostructural materials such as nanotubes, nanowires, and nanorods have recently received much attention due to their interesting properties and are potential candidates for application in different fields. Se nanomaterials have been prepared by different workers using various techniques such as hydrothermal route, chemical vapor deposition, sonochemical approaches, refluxing processes, and cellulose-directed growth [12,13,14,15]. Notable examples including the nanowires of Se via a chemical precipitation method [16], Se nanowires by a hydrothermal technique [17] have been reported. These methods, have several major drawbacks, including the use of toxic chemicals, extreme synthesis conditions involving high-operating temperatures and/or pressures, and highly acidic or alkaline reaction conditions. We report about the preparation and characterization of selenium nanowires using chemical method
