The $x$V$_2$O($1 − x$)[0.8 P$_2$O$_5$·0.2K$_2$O] glass system with $0 \lt x \lt 50$ 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 $x\lt 10$ mol%) and the network former ($x\gt 20$ 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 glasses with $x \lt 20$ mol% V$_2$O$_5$ content was tested by optical density (OD) measurements. A linear correlation between the amount of vanadium and the antibacterial effect was evidenced.
