This work reports on the spectroscopic properties of europium ions intercalated in a vanadium pentoxide matrix, as well as the effects of thermal treatment on its structural and electronic properties. X-ray diffraction. TG/DTA ESR, luminescence as well as XANES were used in order to characterize the intercalation compound. For the as grown samples, the intercalation of Eu~3+ is observed to have little effect in the V_2O_5 lamellar structure, however the inter-planar spacing grows from 1.19 nm to 1.33 nm for a 10
