The xV 2 O(1 − x)[0.8 P 2 O 5 · 0.2 K 2 O] glass system with 0 ≤ x ≤ 50 mol% was prepared and the structural changes induced in these glasses by increasing the vanadium oxide content were investigated by IR and ESR spectroscopies. The dual behaviour role of V 2 O 5 oxide, as network modifier (for x ≤ 10 mol%) and the network former (x ≥ 20 mol%), as a consequence of phosphate network depolymerization and P-O-V and V-O-V linkages appearance was also highlighted. The antibacterial effect of the
