摘要 以乙醇为介质,用二氧化硅球沉降法制备有序性较好的人工欧泊(Opal),并对二氧化 硅球排布进行了显微形貌及透射谱表征.结果显示二氧化硅微球有序堆积,其结构为类面心立 方晶型,与目前的理论研究结果符合得很好. Reports preparation of artificial opal by sedimention of SiO2 spheres in ethanol and it's micro- scopic and optical characterization.Results show that artificial opal belongs to analogue fcc structure,which is in agreement with theoretical calculations by L.V. Woodcock.
