Abstract

Mn-doped ZnO micro structures were successfully prepared by aqueous chemical growth (ACG) method. Mn-doping suppresses axial and radial growth of the pod-like structures due to the differences of Zn and Mn ionic radii and the preferred coordination of Mn in oxides. Mn-doping also leads to the slight increase of the inherent defect-related visible emission of ZnO. All Mn-doped ZnO, however, have maintained their hexagonal wurtzite crystal structure and intense UV emissions. Mn-doping is successfully achieved through a modified ACG method without a highly detrimental effect on the desired properties of ZnO.
