Photoacoustic spectroscopy study on intramolecular energy transfer and relaxation processes of Tb(III) complexes.
The photoacoustic (PA) amplitude spectra and luminescence spectra of different Tb(III) complexes (Tb(AA)3.2H2O Na[Tb(AA)4], Tb(AA)3bpy and Tb(AA)3phen) have been measured, and the PA phase shifts of the different complexes calculated. Combined with the luminescence spectra, the PA amplitude spectra reflected the variation of the luminescence efficiency and the PA phase is directly relative to the relaxation processes. According to the variation of the luminescence efficiency and the phase shift, the intramolecular energy transfer and relaxation processes of different Tb(III) complexes were discussed.
