We propose to drive the NV luminescence chemically, by alternating the surface electric field developed by interacting atoms and molecules with the diamond surface. We demonstrate this phenomenon on oxidized and hydrogenated ND as well as single crystal diamond containing engineered NV centers to the nm-depth. The hydrogenation of NDs leads to quenching of luminescence related to negatively charged (NV-) centers and this way produces changes in the intensity ratio between NV- (636 nm) to neutral NV0 (575nm) centers. We discuss how the reduction of diamond size increases the magnitude of NV color shift mechanism. Pracoviště Fyzikální ústav Kontakt Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Rok sběru 2013
