摘要
一维光子晶体又称布拉格堆积或布拉格反射器,由于其结构简单,制备简便,在材料科学和光学领域得到越来越多的关注。本论文简要的介绍了一维光子晶体,并着重总结了近些年来利用层层组装的方法制备的不同功能性的一维光子晶体,包括基于对水蒸气、有机溶剂、pH、电、磁敏感的响应性一维光子晶体;对多层膜进行修饰改性而具有柔性、超亲水、超疏水、全向抗反射等特殊性质的布拉格堆积;通过在光子结构中引入缺陷层或发光物质,改变其周期性而制备高性能传感器或分布反馈式布拉格激光。此外,我们也讨论了一维光子晶体目前面临的挑战以及未来的应用方向。
One-dimensional photonic crystals(1DPCs) is known as Bragg stacks or Bragg reflectors. Due to its simple structure and easy preparation, it has gained more and more attention in the field of material science and optical science. Herein, we briefly introduce 1DPCs,and emphatically summarize different functional types of 1DPCs prepared by layer-by-layer assembly in recent years, including stimuli-responsive 1DPCs based on water vapor, organic solvents, p H, electrical and magnetic, flexible, superhydrophilic, superhydrophobic or omnidirectional antireflective multilayer structures.Introducing the defect layer or luminescent materials in the photonic structure can change its periodicity and prepare high performance sensor or distributed feedback Bragg laser. Furthermore, we also discuss the current challenges and future application for 1DPCs.
