摘要

It is discovered that the electron paramagnetic resonance (EPR) spectrum of the doubly charged copper centers occurs in single crystals of Pb5Ge3O11 doped with gadolinium or iron after annealing in an atmosphere containing chlorine and bromine. Similar annealing of the crystals doped with copper in a chlorine and fluorine atmosphere leads to redistribution of the intensities of the EPR spectra of two types of Cu2+ centers. The influence of annealing on the ongoing intensity of spectra of the dimeric triclinic centers Fe3+-A, Gd3+-A (where A represent Cl-, Br-, O2-, F-) was the subject of this research. Consideration is given to the mechanisms for changing the charge state and association of copper center with defects.
