Sb. Hong et al., EFFECT OF ALKALI-METAL IONS ON THE INTRAZEOLITIC MIGRATION OF TB(III)IONS IN ZEOLITE-Y, Reaction kinetics and catalysis letters, 57(2), 1996, pp. 291-299
The luminescence spectra of TbLi-Y, TbNa-Y and TbK-Y zeolites treated
at different temperatures are reported. It is found that the intrazeol
itic migration temperature of Tb(III) ions to hexagonal prisms is infl
uenced by the type of the alkali metal ion present together with Tb(II
I) to neutralize the negative framework of zeolite Y.
