Electron Paramagnetic Resonance Laboratory
DiFi Laboratory
Laboratory directed by: Prof. Franco Mario Gelardi

The continuous wave electron paramagnetic resonance spectrometer [Bruker EMX (X-band)] is mainly used to investigate the properties and to estimate the concentration of the paramagnetic point defects (unpaired spins) induced by irradiation in amorphous silicon dioxide (a-SiO₂). In particular, one of the most important reasons of interest of our research group on this technique consists in its peerless ability to obtain detailed information on the microscopic structure of the paramagnetic centers, especially when the system under study involves magnetic nuclei interacting with the unpaired spins. The main technical features of the Bruker EMX spectrometer are reported below.
