minutes) and precise temperature and time control (minute timescales). This RTA approach allows for controlled and highly reproducible formation of specific color centers in type Ib synthetic diamond particles that previously was not possible. Starting with electron-irradiated synthetic diamond particles, controlled production of NV, H3, N3, and mixtures thereof, depending on the annealing temperature (between 700 and 2060 °C), has been demonstrated. The resulting FDPs exhibit fluorescence that covers a broad range of the visible spectrum, from red/NIR fluorescence to blue fluorescence. A systematic study of experimental factors and their influence on specific color center formation is detailed, including annealing temperature, irradiation dose, annealing dwell time, and nitrogen concentration in the starting diamond powder.
In article number https://doi.org/10.1002/adfm.201808362, Olga Shenderova and co‐workers achieve rapid thermal annealing of electron‐irradiated diamond particulates to specific temperatures, which provides controlled and highly reproducible formation of specific color centers in synthetic diamond particles with vibrant luminescence in the red, yellow, green or blue spectral ranges upon increase of the annealing temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
