J.Botsoa, T.Sauvage, B.Courtois, D.De Sousa Meneses, M.F.Barthe, 'Study of nitrogen content in HPHT diamond by nuclear reaction analysis', Nucl. Instr. Meth. Phys. Res. B 450 315-318 (2019) doi:10.1016/j.nimb.2018.05.032

Nuclear reaction analysis (NRA) has been used for the determination of nitrogen content in diamond by monitoring the 14N(d,p0)15N nuclear reaction from a 1.4 MeV deuteron beam incident on the diamond samples. Results obtained in bulk diamond are compared to those inferred from infrared optical transmission measurements. Furthermore, nitrogen content has also been measured by NRA in diamond nanoparticles and in the light of these results we evaluate the conversion of nitrogen to nitrogen-vacancy (NV) complexes in both bulk diamond and diamond nanoparticles after a 2.4 MeV-proton irradiation and subsequent thermal annealing.
