提出了一种通过控制反蛋白石的折射率来连续调节其阻带位置的方法。反蛋白石薄膜的制备使用的单分散的聚苯乙烯球和二氧化硅和二氧化钛的纳米粒子的水悬浮液，然后通过煅烧处理的共组装。改变悬浮液中二氧化硅和二氧化钛的比例，可以微调折射率，从而改变阻带。
A method was developed to continuously adjust the position of the stop band of inverse opal by controlling the refractive index. The inverse opal films were fabricated using a coassembly of monodispersed polystyrene spheres and nanoparticles of silica and titania from aqueous suspensions followed by a calcination treatment. Varying the ratio of silica and titania in the suspensions gave the ability to finely adjust the refractive indices, which as a result changed the stop band.
