DC electrochemical deposition of CdSe nanorods array using porous anodic aluminum oxide template

CdSe nanorods array were prepared using direct current potentiostatic deposition in porous anodic aluminum oxide template from aqueous CdSO4 and H2SeO2 at room temperature (298 K). Electron microscope results show that these CdSe nanorods have a uniform length and diameter. X-ray energy dispersion analysis indicates that the atomic composition of Cd and Se is very close to a 1:1 stoichiometry. X-ray diffraction and electron diffraction pattern investigations demonstrate that CdSe nanorods are a uniform cubic CdSe crystal.
