Zinc oxide （ZnO） is a traditional II-VI semiconductor material. Owing to its direct wide band gap and high exciton binding energy, ZnO has been considered as one of the most promising ultraviolet （UV） lasing materials. Its lasing performance has been widely explored for two decades [1-4]. To realize high-quality high-performance lasers, excellent optical cavities are needed. Among various methods to synthesize ZnO microstructure or nanostructure cavities [5,6], hydrothermal method is considered to be an easy and inexpensive way [6].
