在这项研究中，我们报告了一个简单的溶液相法制备氧化锌纳米结构的可控形貌。以油胺（OAm）和十二烷醇（NO2）为溶剂，在温和的条件下制备了尺寸可调、形状多样（六棱锥、子弹状和贝壳状）的氧化锌纳米晶。同时，预合成的金纳米晶的引入也可以导致金-氧化锌六方纳米锥的杂化纳米结构。此外，还对ZnO纳米结构的形成机理进行了探讨。值得注意的是，具有不同尺寸和形状的ZnO纳米结构的独特的光学性质也进行了讨论。我们希望这一策略能成为制备其他金属氧化物纳米晶的一种普遍而有效的方法。
In this study, we report a simple solution-phase method to prepare ZnO nanostructures with controllable morphologies. By using oleylamine (OAm) and dodecanol (DDL) as solvents, zinc oxide nanocrystals with tunable sizes and diverse shapes (hexagonal pyramids, bulletlike, and pencil-like shapes) have been obtained under mild conditions. At the same time, the introduction of presynthesized gold nanocrystals can also lead to the hybrid nanostructures of gold-zinc oxide hexagonal nanopyramids. In addition, the possible formation mechanism of the as-prepared ZnO nanostructures has been investigated. Notably, the unique optical properties of the ZnO nanostructures with different sizes and shapes have also been discussed. We hope that this strategy will be a general and effective method for fabricating other metal oxide nanocrystals.
