Influence of a static magnetic field on the photoluminescence of an ensemble of Nitrogen-Vacancy color centers in a diamond single-crystal
Ngoc Diep Lai, Dingwei Zheng, Fedor Jelezko +2
We investigate the electron spin resonance of an ensemble of Nitrogen-Vacancy (NV) color centers in a bulk diamond crystal. The four possible orientations of the NV-center in the l…
High nitrogen-vacancy density diamonds for magnetometry applications
V. M. Acosta, E. Bauch, M. P. Ledbetter +10
Nitrogen-vacancy (NV) centers in millimeter-scale diamond samples were produced by irradiation and subsequent annealing under varied conditions. The optical and spin relaxation pro…
A new, enhanced diamond single photon emitter in the near infra-red
Igor Aharonovich, Chunyuan Zhou, Alastair Stacey +6
Individual color centers in diamond are promising for near-term quantum technologies including quantum key distribution and metrology. Here we show fabrication of a new color cente…
Diamond nanoparticles as photoluminescent nanoprobes for biology and near-field optics
A. Cuche, Y. Sonnefraud, O. Faklaris +6
We present results showing the potential of diamond nanoparticles with size less than 50 nm as photoluminescent nanoprobes for serving as stable point-like emitters attached at the…
25-nm diamond crystals hosting single NV color centers sorted by photon-correlation near-field microscopy
Yannick Sonnefraud, Aurelien Cuche, Orestis Faklaris +5
Diamond nanocrystals containing highly photoluminescent color centers are attractive non-classical and near-field light sources. For near-field applications the size of the nanocry…
Photoluminescence of single colour defects in 50 nm diamond nanocrystals
F. Treussart, V. Jacques, E. Wu +3
We used optical confocal microscopy to study optical properties of diamond 50 nm nanocrystals first irradiated with an electron beam, then dispersed as a colloidal solution and fin…
In-situ diagnostics of the crystalline nature of single organic nanocrystals by nonlinear microscopy
Sophie Brasselet, Veronique Le Floc'h, Francois Treussart +4
We elucidate the crystalline nature and the three-dimensional orientation of isolated organic nanocrystals embedded in a sol-gel matrix, using a polarized nonlinear microscopy tech…
