Epr And Optical Absorption Studies On Fe3+ Ions In Alkali Borotellurite Glasses

Electron paramagnetic resonance and optical absorption spectra of Fe3+ ions in 85M2B407.(15-x)Te02.xFe203 glass systems have been studied. The EPR spectra of all glasses exhibit three resonance signals at g=2.0, g=4.2 and g=6.4. EPR spectra of 3 mol% Fe203 doped lithium borotellurite glass system were studied at various temperatures. The intensity of the resonance signals decreases with increase in temperature whereas linewidths are found to be independent of temperature. EPR spectra exhibit a marked concentration dependence on iron content.
