摘要：

X-ray diffraction (XRD), Fourier transform infrared (FTIR), electron paramagnetic resonance (EPR), Ultraviolet-visible (UV-Vis) spectroscopies measurements have been employed to investigate the glasses from the (V2O5)(x)center dot(KPO3)(80-x)center dot(MgO)(19)center dot(Ag2O)(1) (0 <= x <= 10 mol%) system. The studied glasses had a fixed MgO and Ag2O content of 19 mol% and 1 mol% respectively, and the V2(O5):KPO3 ratio was varied. XRD data confirms the vitreous nature of the studied samples. EPR, UV-Vis and IR data confirm the presence of vanadium in multiple valence states.
