Diamondoids can be considered as ideal, surface passivated diamond clusters. They are versatile materials because they can be functionalised by chemical as well as physical means and then self-assembled on surfaces. We propose to study changes in the electronic structure and optical properties of pristine and doped diamondoids to control and exploit their luminescence properties in close cooperation with theory groups. A key aspect is the relationship between functional groups, and doping sites on one side, and wavelength and quantum efficiency of fluorescence light on the other side. Further, we plan to prepare diamondoid-metal cluster hybrids and to investigate the electronic response and coupling between the metals and the diamondoids. Functionalised hybrids are expected to be promising candidates for photonic materials such as bright, nanoscale light emitters.

类金刚石可以被认为是理想的表面钝化的金刚石簇。它们是多功能材料，因为它们可以通过化学和物理手段实现功能化，然后在表面自组装。我们建议与理论小组密切合作，研究原始的和掺杂的金刚烷的电子结构和光学性质的变化，以控制和开发它们的发光性质。一个关键的方面是官能团和掺杂位之间的关系，以及荧光的波长和量子效率之间的关系。此外，我们计划制备类金刚石-金属团簇杂化材料，并研究金属和类金刚石之间的电子响应和耦合。功能化的混合材料有望成为明亮的纳米级发光体等光子材料的候选材料。
