Title: Structural investigation of MO⋅P{sub 2}O{sub 5}⋅Li{sub 2}O (MO = Fe{sub 2}O{sub 3} or V{sub 2}O{sub 5}) glass systems by FTIR spectroscopy

Glasses from the systems xMO⋅(100−x)[P{sub 2}O{sub 5}⋅Li{sub 2}O] (MO = Fe{sub 2}O{sub 3} or V{sub 2}O{sub 5}) with 0 ≤ x ≤ mol % were prepared in the same conditions and characterized by IR spectroscopy. It was established the mode in which both Fe{sub 2}O{sub 3} and V{sub 2}O{sub 5} influences the local structure of these glasses. The iron ions generally modify in a different way the local structure of these glasses then vanadium ions. The results shown that phosphate units are the main structural units of glass system and the iron and vanadium ions are located in the network.
