Large scale synthesis of cadmium selenide nanowires using template synthesis technique and their characterization

摘要

We report the fabrication, and structural and optical characterization of CdSe nanowires. Large scale uniform nanowires with length 40 micron and diameter 100 nm were grown using the simple chemical reaction technique. Morphological study of CdSe nanowires was done using scanning electron microscopy (SEM). X-ray diffraction (XRD), and Raman studies show the crystalline structure of CdSe nanowires. Energy dispersive X-ray fluorescence (EDXRF) technique was used to study the composition of CdSe nanowires. UV-Vis absorption studies show a blue shift of 0.26 eV in the optical band gap of CdSe nanowires.
