Tailor-made, adjustable photonic crystals and glasses are to be produced by atomic layer deposition. First, spherical and cylindrical nanostructures will be coated with a defined sequence of isotropic oxide layers in order to generate an effective radial anisotropic refractive index of the elementary base unit and thus precisely adjust the scattering properties of the photonic structures. Second, metal-insulator phase transition materials will be used for the coating of pre-assembled photonic structures. These materials allow for a (controllable) temperature-dependent switching of the optical properties of the photonic structures.

定制的、可调节的光子晶体和玻璃将通过原子层沉积来生产。首先，球形和圆柱形纳米结构将涂有确定序列的各向同性氧化物层，以便产生基本基本单元的有效径向各向异性折射率，从而精确调整光子结构的散射特性。其次，金属-绝缘体相变材料将用于预组装光子结构的涂层。这些材料允许光子结构的光学特性进行（可控的）温度依赖性切换。
