英文摘要：

The nanocrystalline zinc oxide （ZnO） microspheres were prepared through the thermal alconolysis reaction of zinc acetate in diethylene glycol （DEG）, and photonic crystals of the zinc oxide opal were obtained by the self-assembly of the microspheres. The effect of beating rate on the alcoholysis temperature, the microsphere size and its distribution were investigated under the scanning electronic microscope （SEM） and transmission electronic microscope （TEM）. Based on the alcoholysis method, zinc oxide microspheres were prepared by using seed solution as nucleus to induce the formation of the spheres, and the influence of seed solution amount added and reaction time on the size of zinc oxide microspheres were also discussed. The core-shell microspheres by using silica gel, silica colloid or polystyrene colloid as core （seed solution） and ZnO as shell were also explored.
