Abstract

CdSe nanowires were prepared by a simple DC electrochemical process using porous anodic alumina templates. FESEM micrographs demonstrated the growth of CdSe nanowires of diameter 200-300 nm by filling up the nano-pores in alumina. X-ray diffraction patterns revealed the growth of CdSe with hexagonal phase. The absorption spectrum showed a band gap value nearer to bulk CdSe. Room temperature photoluminescence measurement showed the defect related emission from the nanowires.
