Abstract

Post-growth annealing improves the crystal and optical qualities of ZnO micro structures fabricated by carbothermal reduction method. Annealing at 400 and 800 °C leads to better crystallinity and intense UV emission of the ZnO samples. The defect-related visible emission, however, still persists even after annealing at high temperatures. The post-growth annealing of carbothermal-grown ZnO is an effective method to produce better quality UV emitting ZnO microstructures for optoelectronic applications.
