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.
测量了不同Tb(III)配合物(Tb(
AA)3.2H2O Na [Tb(
AA)4],Tb(
AA)3bpy和Tb(
AA)3phen)的光声(PA)振幅光谱和发光光谱,并且计算出不同配合物的PA相移。结合发光光谱,PA振幅光谱反映了发光效率的变化,并且PA相位与弛豫过程直接相关。根据发光效率和相移的变化,讨论了不同Tb(III)配合物的分子内能量转移和弛豫过程。
