Quenching nitrogen-vacancy center photoluminescence with infrared pulsed laser

Autor: Lai, N. D., Faklaris, O., Zheng, D., Jacques, V., Chang, H. -C., Roch, J. -F., Treussart, F.

Diamond nanocrystals containing Nitrogen-Vacancy (NV) color centers have been used in recent years as fluorescent probes for near-field and cellular imaging. In this work we report that an infrared (IR) pulsed excitation beam can quench the photolumi

Diamond particles as nanoantennas for nitrogen-vacancy color centers

Autor: Greffet, J. -J., Hugonin, J. -P., Besbes, M., Lai, N. D., Treussart, F., Roch, J. -F.

The photoluminescence of nitrogen-vacancy (NV) centers in diamond nanoparticles exhibits specific properties as compared to NV centers in bulk diamond. For instance large fluctuations of lifetime and brightness from particle to particle have been rep

A recent experiment performed by S. S. Afshar et al. has been interpreted as a violation of Bohr's complementarity principle between interference visibility and which-path information in a two-path interferometer. We have reproduced this experiment,
