Tuning of SiV quantum emission in nitrogen-doped nanodiamonds by dual-color excitation
A. A. Zhivopistsev, A. M. Romshin, A. V. Gritsienko +8
The charge dynamics of silicon-vacancy (SiV) centers have been investigated for the first time in high-pressure high-temperature nanodiamonds (NDs) with varying concentrations of s…
Single-photon sources created by nature millions of years ago
D. G. Pasternak, A. M. Romshin, R. A. Khmelnitsky +6
Single photons source (SPS) is a key component required by quantum communication devices. We report the finding of bright diamond-based SPS created by nature millions of years ago.…
Donor-acceptor recombination emission in hydrogen-terminated nanodiamond: Novel single-photon source for room-temperature quantum photonics
D. G. Pasternak, A. M. Romshin, R. H. Bagramov +9
In fluorescence spectra of nanodiamonds (NDs) synthesized at high pressure from adamantane and other organic compounds, very narrow (~1 nm) lines of unknown origin are observed in…
Raman fingerprints of ultrasmall nanodiamonds produced from adamantane
O. S. Kudryavtsev, R. H. Bagramov, A. M. Satanin +4
The synthesis of ultrasmall (2-5 nm) nanodiamonds purely from adamantane at pressure of 12 GPa is reported. Their structural features have been studied by Raman spectroscopy. The u…
Highly Boron-Doped Graphite and Diamond Synthesized From Adamantane and Ortho-Carborane under High Pressure
Rustem H. Bagramov, Vladimir P. Filonenko, Igor P. Zibrov +4
This work demonstrates the effectiveness of the high-pressure method for the production of graphite and diamond with a high degree of boron doping using adamantanecarborane mixture…
Fano-type effect in hydrogen-terminated pure nanodiamond
O. S. Kudryavtsev, R. H. Bagramov, A. M. Satanin +7
Two novel properties, unique for semiconductors: a negative electron affinity [1-2], and a high p-type surface electrical conductivity [3-4], were discovered in diamond at the end…
A new tool for precise mapping of local temperature fields in submicrometer aqueous volumes
Alexey M. Romshin, Vadim E. Zeeb, Artem K. Martyanov +6
Nanodiamond hosting temperature-sensing centers constitutes a closed thermodynamic system, with the only window of energy exchange with the environment without direct contacts of a…
