Towards Selective Functionalization of Diamonds — •Anke Lämmle, Bernhard Grotz, Rolf Reuter, Fedor Jelezko, and Jörg Wrachtrup — 3. Physikalisches Institut, Universität Stuttgart, Germany

In recent years diamonds have attracted high attention in several fields. Out of many colour centres that can be incorporated in diamond, the nitrogen-vacancy centre (NV) has let in particular nanodiamonds make inroads into such diverse fields like biology [1], magnetometry [2] and single photon plasmonics [3,4]. Using diamonds with NV centres is favorable because it combines an unmatched photostability with chemical inertness, biocompatibility and hardness. However further experiments require a deeper knowledge about surface functionalization and its impact on the NV centre itself. We discuss first steps that might lead to a selective functionalization of diamond surfaces and potential applications.
