【Abstract】 In this paper,XRD and PL of zinc oxide one dimensional nanomaterials with different morphologies synthesized at low temperature by liquid phase reaction,such as nanowire bundles shaped like an awl,spindle- like microcrystals,flower- like nanostructures,nanorod arrays with the hexagonal top and micro / nanotube arrays with a hexagonal shape are analyzed. The results show that the emission of near band edge is enhanced by controling an optimal growth surface( 002),in the meantime,PL of emission of visible light can be enhanced by controling the growth surface( 110) and increasing the defects of Lattice.更多还原
