In this report, a technique for rapid synthesis of ZnO microstructures by microwave-assisted heating of precursors at hydrothermal conditions is demonstrated. Further, the reaction mechanism for the growth of ZnO microstructures is analyzed. An accelerated rate of reaction obtained using microwaves enables a dissolution-recrystallization mechanism for generation of one dimensional (1D) rod-like structures, thereby showing that time of reaction can be used to dictate ZnO microstructure morphology.
在本报告中，展示了一种通过在水热条件下微波辅助加热前驱体来快速合成ZnO微结构的技术。此外，还分析了ZnO微结构生长的反应机理。利用微波获得的加速反应速率实现了一维（1D）棒状结构生成的溶解-重结晶机制，从而表明反应时间可用于控制ZnO微结构的形态。
