在乙醇介质中制备SiO2光子晶体及其表征

Preparation and Characterizaion of Silica Photonic Crystals Made from Ethanol

    摘要
  • 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.

     

    Abstract: Reports preparation of artificial opal by sedimention of SiO2 spheres in ethanol and it's microscopic and optical characterization.Results show that artificial opal belongs to analogue fcc structure,which is in agreement with theoretical calculations by L.V. Woodcock.
