摘要：

The effect of air annealing on the luminescence, native defects, and morphology of ZnO powder prepared through pyrolysis of a zinc nitrate solution is studied at annealing temperatures from 100 to 1000 degrees C. The results indicate that annealed ZnO is only enriched in oxygen at annealing temperatures below 200 degrees C. During annealing at higher temperatures, ZnO loses predominantly oxygen, which gives rise to green luminescence. The green band is shown to consist of several components. According to electron microscopy results, high-temperature annealing drastically increases the particle size of the ZnO powder.
