摘　　要：运用溶胶-凝胶法制备了不同粒径单分散SiO2纳米微球,垂直沉积法制备了SiO2三维光子晶体薄膜.通过SEM研究了SiO2光子晶体的微观结构,探讨了薄膜内裂痕形成原因与克服办法.通过分光光度计测定了光子晶体的带隙位置,与理论计算相吻合.光子晶体带隙随着SiO2微球粒径增加带隙红移.The different diameters of SiO2 are synthesized by sol-gel method. The three dimension photonic crystals are obtained by the vertical deposition method. The nano-structure of the SiO2 photonic crystals is detected by SEM. The causes and avoid approaches of the cracks within the film are explored. The handgaps of the photonic crystals are located by the spectrophotometer. The location of the bandgaps coincides with the theoretical calculation. The bandgaps is redshihed with the increasing of the diameter of the SiO2.
