ELECTRON-SPIN-RESONANCE OF TRANSITION-ELEMENTS IN FLUORIDE AND OXYFLUORIDE GLASSES

A review of the ESR studies on transition elements (Ti, V, Cr, Mn, Fe, Co, Ni, and Cu, along with Gd and Eu) in different fluoride glasses, namely, fluoroberyllate, fluorozirconate, fluorohafnate, and fluoroaluminate glasses and in oxyfluoride glasses, namely, fluorogermanate, fluoroborate, fluorophosphate, etc., is reported. The findings of investigations into the transition-element states in the fluoride glass matrices provide interesting and useful information on the nature of vitreous state.
