Single‐crystalline Sb shallow‐doped ZnO microwire wave‐guided optical resonators are synthesized via a simple carbothermal reduction method. The formation of the ZnO wave‐guided microcavities are investigated systematically, and the Sb film formed on the substrate is confirmed to be the critical factor in crystal growth. The optical signals of the annealed ZnO microcavities induced by the Sb related acceptor defects are clarified through a low‐temperature spectrum detection technology. Excitation power and temperature dependence of UV lasing properties of the ZnO microcavities annealed in different atmospheres are studied. The results reveal that such high‐quality Sb shallow‐doped ZnO wave‐guided microcavities have excellent optical responses and a strong light‐field regulation capability, which would greatly promote the development of ZnO cavity‐based photoelectronic devices.
