摘　　要：采用改进的Stber法合成了不同粒径的单分散SiO2微球颗粒,用种子液法制备了平均粒径约为550 nm的单分散SiO2微球颗粒,在可见光波段垂直沉积制备了SiO2光子晶体薄膜。采用紫外-可见分光光度计测试了不同反应物浓度配比所得微球制备的光子晶体薄膜的光学性能,并分析了退火对光反射性能的影响。The uniform SiO2 particles with different diameter were synthesized by modified Stber method,and particles with the diameter of 550 nm were synthesized by seed solution method. SiO2 photonic crystals in visible range were fabricated by vertical deposition. Optical properties of SiO2 photonic crystals were measured by UV-Vis spectrometer and influence of annealing on the optical reflectance were studied.
