Abstract
The presence of different vanadium species in VSi beta zeolite is evid enced by diffuse reflectance UV-visible and photoluminescence spectros copies, but only the latter is able to clearly distinguish three kinds of tetracoordinated vanadium sites and to reveal the effects of V loa ding and dehydration-hydration processes on the environment of the V s pecies.
