基于纳米粒子的一维光子晶体
【纳米科技世界快讯】最近，西班牙的科学家构造了一种基于纳米粒子来构造一维光子晶体的新方法。他们通过用纳米粒子层中孔隙率和不同的纳米粒子来调制器穿过光学层的光学特性。具体论文发表在Langmuire杂志上。
Abstract:
Herein we present a fast, reliable method for building nanoparticle-based 1D photonic crystals in which a periodic modulation of the refractive index is built by alternating different types of nanoparticles and by controlling the level of porosity of each layer. The versatility of the method is further confirmed by building up optically doped photonic crystals in which the opening of transmission windows due to the creation of defect states in the gap is demonstrated. The potential of this new type of structure as a sensing material is illustrated by analyzing the specific color changes induced by the infiltration of solvents of different refractive indexes.
