Liquid Crystalline Soft Photonic Materials

项目摘要

Liquid crystals are well-known for their applications in display devices. Nonetheless, they are great photonic materials too. Photonic structures made with liquid crystals, polymers and gels offer number of advantages including mobility, selfassembly, tuneability and ease of manufacturing. Hence there is a huge interest to develop novel methods of producing soft photonic structures, understanding their dynamics in guest-host systems. On the other hand, the behavior of the luminogens when suspended in liquid crystal media is extremely interesting. Generally, after a critical concentration, they tend to aggregate into nano-sized clusters and these nanoaggregates quench the luminescence property of the suspension. The aim of this project is to achieve responsive soft photonic systems which exhibit multimode optical properties such as scattering and emission for the next generation displays and sensors using liquid crystals as a templating medium. The project will involve careful chemical and electrical tailoring of the liquid crystal based composite materials. The student will work on engineering and understanding the physics of soft photonic materials, establish procedures to encapsulate photonic materials though microfluidics, understand the dynamics such as swelling and de-swelling of enclosures by systematic scattering and dynamics studies along with developing new device prototypes.

液晶因其在显示设备中的应用而广为人知。尽管如此，它们也是很好的光子材料。由液晶、聚合物和凝胶制成的光子结构具有许多优点，包括移动性、自组装、可调谐和易于制造。因此，开发新的方法来产生软光子结构，了解它们在客体-宿主系统中的动力学，是一个巨大的兴趣。另一方面，当发光体悬浮在液晶介质中时，其行为非常有趣。通常，在临界浓度后，它们倾向于聚集成纳米级的团簇，这些纳米聚集体抑制了悬浮液的发光性能。该项目的目标是实现响应的软光子系统，该系统具有多模光学特性，如散射和发射，用于使用液晶作为模板介质的下一代显示器和传感器。该项目将涉及液晶基复合材料的精心化学和电气裁剪。学生将致力于工程设计和理解软光子材料的物理，建立通过微流体封装光子材料的程序，通过系统的散射和动力学研究了解外壳的膨胀和消胀等动力学，同时开发新的设备原型。
