Abstract
The photoacoustic spectra(PAS) of the coprecipitates Tb3+-Gd3+-Sal com plexes are reported. With the increase of the concentration of Gd3+ io n, the PA intensity of complexes decrease firstly, then increase. It i s indicated that the addition of the second rare earth ion Gd3+ change s the relaxation processes of the complexes. The changes of the fluore scence spectra turn out complementary to the PAS. The intramolecular e nergy transfer and the intermolecular energy transfer processes in cop recipitates are discussed.
