It is the goal of this proposal to develop methods for the preparation of functional, structured three-dimensional photonic crystals for the use in the visible wavelength region. To perform this task we will template films of crystallized polymerlattices, because they are rather flexible with regard to structuring. At the same time they are interesting model systems. During the duration of the 'Schwerpunkt' (6 years) we will tackle problems like (i) the epitaxy of polymer beads to produce heterostructures, (ii) the controlled incorporation of threedimensional defects and (iii) light emission inside a photonic structure. The basis for this work is the synthesis of various functional monodisperse polymer beads. The methods for their crystallization will be improved with the emphasis on the development of methods for an epitactical crystallization of different polymerlattices to create heterostructures. Ways for structuring/patterning of the photonic films (e-beam, ion-beam and X-ray lithography) will be investigated as well as the formation of inorganic templates or metallodielectrics to open a full photonic bandgap in the visible region. With regard to functionalization we will especially work on the infilling with organic semiconductors (organic LEDs with a photonic structure) and on switchable photonic structures (rubbery constitution, which can be deformed mechanically).

本提案的目标是开发用于制备在可见波长区域中使用的功能性、结构化三维光子晶体的方法。为了完成这项任务，我们将模板薄膜结晶聚合物晶格，因为他们是相当灵活的结构方面。同时，它们也是有趣的模型系统。在“Schwerpunkt”（6年）期间，我们将解决以下问题：（i）聚合物珠的外延以产生异质结构，（ii）三维缺陷的可控结合和（iii）光子结构内部的光发射。这项工作的基础是合成各种功能性单分散聚合物珠粒。其结晶的方法将得到改进，重点是开发不同聚合物晶格的外延结晶方法以产生异质结构。将研究光子膜的结构化/图案化（电子束、离子束和X射线光刻）的方法以及无机模板或金属化物的形成以在可见光区域中打开完整的光子带隙。关于功能化，我们将特别致力于有机半导体（具有光子结构的有机LED）的填充和可切换的光子结构（橡胶结构，可以机械变形）。
