“…NV centers occur naturally in nanodiamonds from high-pressure high-temperature (HPHT) synthesis, but their numbers can be increased by irradiation in several different ways. These increase the number of color centers and thus their fluorescence intensity [4]. Possibilities include irradiation with silicon ions [5], helium ions [6], or electrons [7,8].…”

“…As a result, there are numerous efforts to manufacture small, bright, and high-purity NDs that differ by size, nitrogen content and surface chemistry; these ND samples display different NV center emission spectra and intensity levels due to interactions with the surface, or due to a different number of NV centers per particle. 22,23 For these reasons, the photophysical characterization of NDs is crucial to ensure successful applications in bioimaging, especially using single-molecule microscopy. Further, since NDs are increasingly implemented in quantum technologies, the characterization of NV centres in NDs is an important endeavor, as most of our knowledge on the photophysics of the NV centre originated from studies performed in bulk diamond.…”

“…Alternatywnym sposobem bioobrazowania z użyciem NDs jest wykorzystanie ich centrów barwnych, czyli naturalnych bądź wprowadzonych sztucznie defektów krystalicznej struktury, posiadających zdolność do absorpcji i emisji światła w temperaturze pokojowej [79]. Ze względu na najczęściej występujące zanieczyszczenia NDs azotem, większość badań koncentruje się na wykorzystaniu nanocząsteczek, których centra barwne składają się z azotu i wakancji [94]. Centra te charakteryzują się silną absorpcją światła o długości fali 550 nm oraz stabilną emisją fluorescencji [95].…”
