Wurtzite zinc oxide (ZnO) nanochains have been synthesized through high-pressure pulsed laser deposition. The chain-like ZnO nanostructures were obtained from magnesium (Mg) doped ZnO targets, whereas vertically aligned nanorods were obtained from primitive ZnO targets. The Mg doping has influenced the morphological transition of ZnO nanostructures from nanorods to nanochains. The field emission scanning electron microscope images revealed the growth of beaded ZnO nanochains. The ZnO nanochains of different diameters 40 and 120Â nm were obtained. The corresponding micro-Raman spectra showed strong E2H mode of ZnO, which confirmed the good crystallinity of the nanochains. In addition to near band edge emission at 3.28Â eV, ZnO nanochains show broad deep level emission at 2.42Â eV than that of ZnO nanorods.
