Abstract: Ce(Ⅲ)-Tb(Ⅲ) exchanged zeolites have been synthesized by aqueous solution ion exchange procedures.The spectral behaviour and concentration quenching of Ce(Ⅲ) and Tb(Ⅲ) luminescence are discussed.The energy transter between trivalent rare-earth ions in ze olite host has been originally observed.The energy transfer process is systematically investi gated by luminescence spectra and luminescence lifetime experiments The mechanism of energy transfer is proposed based on the radiationless electric multipole-multipole interaction in this system.

Key words: Ce(Ⅲ), Tb(Ⅲ), Zeolite, Luminescence, Energy transfer
