Abstract
The luminescence spectra of TbLi-Y, TbNa-Y and TbK-Y zeolites treated at different temperatures are reported. It is found that the intrazeolitic migration temperature of Tb(III) ions to hexagonal prisms is influenced by the type of the alkali metal ion present together with Tb(III) to neutralize the negative framework of zeolite Y.
