Europium-exchanged synthetic faujasite zeolites: A luminescence spectroscopic study

A series of thermally activated europium-exchanged X and Y zeolites have been characterized by luminescence spectroscopy. The distribution of Eu(III) species has been deduced for both EuX and EuY samples (held at 20 K), on the basis of the observed 5D 0 → 7F 0 luminescence emissions. For thermally a...
