Room temperature triggered single-photon source in the near infrared

Abstract: We report the realization of a solid-state triggered single-photon source with narrow emission in the near infrared at room temperature. It is based on the photoluminescence of a single nickel-nitrogen NE8 colour centre in a chemical vapour deposited diamond nanocrystal. Stable single-photon emission has been observed in the photoluminescence under both continuous-wave and pulsed excitations. The realization of this source represents a step forward in the application of diamond-based single-photon sources to Q… Show more

“…A multitude of color centers containing nickel is known, especially in nitrogen rich high pressure high temperature (HPHT) diamond, where nickel is used as a catalyst and forms several complexes with nitrogen [69] . The only of these complexes identified as single emitter is the so called NE8 center [70][71][72] , consisting of a nickel atom, two vacancies and four nitrogen atoms. The ZPL for single NE8 centers has been reported between 782 and 802 nm.…”

“…To move beyond the limitations of the NV center, alternative diamond based single photon emitters such as the silicon vacancy (SiV) [20] or the nickel related complex (NE8) [27][28][29] have been investigated. However, the very low emission rates of the SiV center, and the difficulty of controllably fabricating these centers at the single center level, has motivated the search for alternative diamond based single photon sources.…”

“…Биосовместимость, химическая инерт-ность, низкая токсичность и возможность химической функционализации поверхности наноалмазов открыва-ет перспективу применения наноалмазов с центрами окраски для биомедицины [7]. В алмазных пленках и частицах, полученных методом химического газофазного осаждения (chemical vapor deposition-CVD), наиболь-ший интерес прикован к следующим центрам окраски: кремний−вакансия (SiV) [9][10][11][12][13][14][15][16][17][18][19][20], Ni-содержащим [21][22][23][24][25], Сr-содержащим [26][27][28], азот−вакансия (NV) [29,30]. Недавно в спектрах ФЛ в алмазе, полученном методом CVD, обнаружены узкие линии ФЛ [31][32][33], структура и механизм формирования которых остаются не до конца установленными.…”
