摘要/Abstract

摘要： 用旋涂法将聚苯乙烯微球组装成光子晶体,研究了此光子晶体的特点,并分析了在单一微球粒径下旋涂参数对光子带隙的影响.结果表明:旋涂法制备的光子晶体具有各向同性特点,其光子带隙由旋涂参数决定.光子晶体的反射波段取决于乳液中微球的质量分数,而反射强度取决于旋涂层数.因此,在设计光子晶体时,可以根据需要,通过微球的质量分数和旋涂层数的改变实现对光子带隙的控制.

Abstract: In this study, polystyrene microspheres assembling photonic crystals were fabricated by spin coating. Features of photonic crystals were studied, and the influence of different parameters on photonic band gap with a certain size microspheres was analyzed. The results showed that: photonic crystals fabricated by spin coating presented isotropic characteristics, and the photonic band gap of photonic crystal could be controlled by changing parameters. The reflection band of photonic crystal depended on mass fraction of microspheres, and the intensity depended on layers of spin coating. Consequently, we can control the photonic band gap via changing mass fraction of microspheres and layers of spin coating according to the requirement during designing the photonic crystal.

Key words: spin coating, vertical deposition, isotropic, three-dimensionally ordered, tunable photonic band gap, photonic crystal
