Abstract
(100-x)B2O3.xLi(2)O (mol%) glasses with x=0-50 were prepared by conven tional melting technique and exposed to gamma-ray in irradiation. The CW-EPR spectra were recorded at room temperature and show a strong dep endence on x. Echo induced EPR spectrum of the B2O3 glass is different from the CW-EPR spectrum showing better resolution. The FID spectrum of this centre contains valuable information about the structure of th is centre. Analysis of 3D FT-EPR spectra of these glasses demonstrated the influence not only of boron but also of hydrogen on the creation of these EPR spectra. Such influence was neglected in the past.
