ESR Imaging of Paramagnetic Defect Centers in Quartz Glass

Abstract

Abstract: The spatial distributions of paramagnetic defect centers Fcenters in quartz Dewar after UV-irradiation were detected by ESRimaging method.It has been shown that the spatial distributions of Fcenters in the quartz Dewar are non-uniform from ESRspectrum with magnetic field gradient and 2-D ESRimages.The concentration of Fcenter is colsely related to the irradiation direction and density.The geometric size of the cross section of Dewar obtained by calculating ESRdiscrete point map of Fcenter is in agreement with the material object.
