Morphology Controlled Synthesis of Tubular Cu-doped ZnO Twinned Structure Materials For Photoluminescence Property

摘要: 采用直接沉淀法合成了具有六棱柱体形貌的Cu2+掺杂ZnO双晶结构材料，研究了Cu2+的存在对ZnO双晶的形成及形貌的影响，发现溶液中存在的Cu2+浓度越高，获得的Zn(Cu)O材料粒径越大，形貌从细长棒形逐步变为短粗六方柱体，长径比也从10:1变到1.2:1。采用简单的碱腐蚀法获得了管状结构的Cu2+掺杂Zn(Cu)O材料，并探讨了管状结构的形成机理。Cu掺杂使得Zn(Cu)O样品的绿光发射由550nm蓝移至520nm附近，且强度大幅增加。形成管状结构使绿光发射进一步增强，该发射由Cu2+掺杂引起的样品内部的Cu2+与Cu+之间的相互转变引起。

Abstract: The Cu-doped ZnO twinned structure materials with hexagonal prism morphology were synthesized by direct precipitation and the effects of Cu2+ ion on the formation of twinned structure and morphology were investigated. With the increase of Cu2+ concentration in reaction solution the particle sizes of as-prepared ZnO materials increased following the change of morphologies from slender rod to stumpy hexagonal prism and the decrease of length-diameter ratios from 10:1 to 1.2:1. The tubular Cu-doped ZnO materials were obtained via corroding process by concentrated aqueous alkali and the formation mechanism was proposed. The photoluminescence properties of Zn(Cu)O materials were studied and the Cu-doped ZnO showed broad and strong green emission at 520 nm, attributed to the transition of copper ion between Cu2+ and Cu+ in interior of ZnO crystal. The formation of tubular construction enhance the intensity of green emission.-
