结果表明，在直径为220 nm的聚苯乙烯胶体溶液中，水的低速准平衡蒸发可以在不引起晶格显著扭曲的情况下制备三维胶体-空气光子晶体结构，并在500 nm附近观察到该结构的吸收峰。由于介电对比度增加了约30%，预计会有更强的光子带隙效应。
We demonstrated that low-velocity quasi-equilibrium evaporation of water from an aqueous colloidal solution of polystyrene microparticles with 220 nm diameter enabled the preparation of a three-dimensional colloidal-air photonic crystal structure without significantly distorting the lattice, and the absorption peak of the structure was observed at around 500 nm. A much stronger photonic band gap effect is expected due to an approximately 30% increase of the dielectric contrast.
