The project aims at the application of photonic crystals of biological origin for controlling the adsorption and emission of light. As prototypical example, the diatom Coscinodicus granii is chosen, the silicea cell wall of which exhibits a very regular hexagonal pore structure. The chemical structure of the cell wall allows covalent junctions for implementation into silicon microtechnology and the attachment of functional organic dyes as optically active components. In the project, the light path within a diatom cell structure and the local efficiency of light adsorption and emitting is investigated. The possibility of obtaining determined feature sizes by means of cell culivation will be explored.

该项目旨在应用生物来源的光子晶体控制光的吸收和发射。作为典型的例子，选择硅藻Coadenodicus granii，其silicea细胞壁表现出非常规则的六边形孔结构。细胞壁的化学结构允许用于实施硅微技术的共价结和作为光学活性组分的功能性有机染料的附着。本计画主要研究硅藻细胞结构内的光路以及光吸收与发光的局部效率。将探讨通过细胞培养获得确定的特征尺寸的可能性。
