摘要：
Paramagnetic centers in nano Si3N4 particles and their nature were comparatively studied before and after neutron irradiation. Electron Paramagnetic Resonance (EPR) spectroscopic analysis was performed at magnetic field values of 0.05-0.55 T (500-5500 Gauss). The 3460G-3580G area corresponding to Si-based paramagnetic centers is discussed in detail. After neutron irradiation some annihilated EPR signal explained. The formation mechanisms of Si-Si, Si-3 equivalent to Si* and Si equivalent to N-3-based paramagnetic centers and the effect of neutron-induced transmutation on them has been studied.
