Abstract
Highly ordered CdSe nanowires constituted from nanocrystallites (nanoparticles) have been successfully prepared using simple chemical route in paired cell using Anodic Alumina Membrane (AAM) as a template, cadmium sulphate as cation precursor in the presence of suitable complexing agent and Na2SeSO3 as Se precursor, respectively. The nanowires were characterized by SEM, EDAX, XRD and UV–Vis spectroscopic techniques. X-ray diffraction pattern indicates that the CdSe nanowires are grown with nanocrystalline cubic zinc blende structure. UV–Vis absorption spectrum is used to find out the optical band gap of nanowires which is found to be 2.25 eV.
