Established the nature of the vacancy defects, defined their spectroscopic properties (g || = 2.0180, g = 2.0088) and concentration dependence on the dose and erbium content. With measurements of magnetic susceptibility, the presence of two subsystems - paramagnetic and ferromagnetic caused by isolated ions Er3 + clusters and erbium, respectively. Based on the analysis of PL spectra of the model of 4f-4f transitions to power erbium ions in the glass exposed - considering the important role of cross-relaxation processes. It is shown that the increase in the concentration of radiation defects and erbium clustering significantly affect the radiative properties of glasses. Product Description popup.authors І.Б.
