Abstract
It is found that the onset of photoinduced centers in glassy GeS2.2 le ads to chaotic changes in the signal in the long-wavelength region of the electroabsorption spectrum. It is shown that the application of no ise spectroscopy methods to the analysis of the photoinduced signal ma kes it possible to determine the energy position of four levels of pho toinduced centers, lying near the center of the band gap. The model of electron-hole pairs localized on defects is used to explain the posit ion of the levels. (C) 1997 American Institute of Physics.
