给出了一种制备聚苯乙烯小球蛋白石结构光子晶体,并运用单层聚苯乙烯小球为模板制备了一系列二维光子晶体的方法,包括α-Fe2O3二维碗状光子晶体和ZnO柱二维光子晶体结构,并通过大面积反射谱测量了聚苯乙烯胶体光子晶体的光子带隙.聚苯乙烯小球模板法制备方法简单,成本低,重复性好,而且是大面积生长,为制备各种形貌的二维光子晶体提出了新思路.
Polystyrene photonic crystal and a series of two-dimensional (2D) photonic crystals based on polystyrene template were prepared, including two-dimensional photonic crystal of α- Fe2 O3 bowls and two-dimensional photonic crystal of ZnO pillars. Large-area specular reflectance measurements showed the presence of photonic stop band. Self-assembled PS is a simple, low cost and repeatability method to fabricate large-area two-dimensional photonic crystal. It offers a new idea on preparing two-dimensional photonic crystal.
