Abstract
The magnetic susceptibility of Eu1-xYxVTa2O9 (0 < x < 0.20) solid solutions was found to vary nonmonotonically with Y content. This result was interpr eted as due to changes in the proportion of V4+ ions. Increasing the synthe sis temperature from 1100 to 1300 degreesC was shown to raise the proportio n of V4+ in EuVTa2O9 from 9.87 to 12.03%. The highest light yield was obser ved at x similar or equal to 0.05, corresponding to the smallest V4+/V5+ ra tio.
