Abstract

Paramagnetic centers in the nanocrystalline boron nitride (h-BN) particles were comparatively studied before and after neutron irradiation. Electron Paramagnetic Resonance (EPR) spectroscopic analyzes were performed in the broad range of magnetic field from 0.05 to 0.55 T (500–5500 Gauss). The range of 0.3270–0.3370 T was additionally sweeped, where more paramagnetic centers were observed. The nature of the new paramagnetic centers formed as a result of neutron transmutation in the BN nanoparticles were examined by EPR spectra. Formation mechanism of VB and VN vacancies has been studied in detail by neutron transmutations.
