Electron spin resonance detection and identification of nitrogen centers in nanodiamonds
Individual nitrogen centers N 0 and nitrogen pairs N 2 + have been detected and identified in natural diamond nanocrystals by means of the high-frequency electron spin resonance method. The N 0 nitrogen centers have been observed in synthetic diamond nanocrystallites with a size of less than 10 nm p...

Summary: | Individual nitrogen centers N
0
and nitrogen pairs N
2
+
have been detected and identified in natural diamond nanocrystals by means of the high-frequency electron spin resonance method. The N
0
nitrogen centers have been observed in synthetic diamond nanocrystallites with a size of less than 10 nm produced by high-temperature high-pressure sintering of detonation nanodiamonds. Thus, the possibility of the stable state of impurity nitrogen atoms in diamond nanoparticles has been demonstrated. |
