Abstract:Cobalt-doped ZnO nanorods were successfully synthesized on SiO2/Si substrate using RF-magnetron sputtering at room temperature. The structural, morphological, and photoluminescence (PL) properties of undoped and Co-doped ZnO nanostructure were characterized using X-ray diffraction, field emission-scanning electron microscopy, and PL analyses. The results showed that Co2+ replaces Zn2+ in the ZnO lattice without changing the wurtzite structure. As the Co concentration increases, the structure becomes highly cry… Show more
