The effects of neutron irradiation on paramagnetic centers in nanocrystalline h-BN particles were investigated using EPR spectroscopy. The formation of new paramagnetic centers in h-BN nanoparticles induced by neutron flux was explained by EPR spectra.
Paramagnetic centers and their character in the nanocrystalline h-BN particles were investigated before and after neutron irradiation. Color changing in a neutron irradiated h-BN nanoparticles was analyzed by new formed EPR signal. Electron Paramagnetic Resonance (EPR) analysis was performed at room temperature in the range of 500 divided by 5500 G with 3300 G central line. The 0.3270-0.3370 T region, where more paramagnetic centers are observed, was additionally considered. New paramagnetic centers formed by the neutron flux in h-BN nano-particles have been explained by EPR spectra.
