摘要：

The presence of different vanadium species in VSi beta zeolite is evidenced by diffuse reflectance UV-visible and photoluminescence spectroscopies, but only the latter is able to clearly distinguish three kinds of tetracoordinated vanadium sites and to reveal the effects of V loading and dehydration-hydration processes on the environment of the V species.
