In this study, a detailed photophysical characterization of the [Tb(H2O)9]3+aqua ion was performed. The luminescence quantum yield (φlum), excited state lifetime (τobs), radiative (krA) and nonradiative (knr) rate constants, and oscillator strength (f) were determined for Tb(CF3SO3)3in H2O/D2O mixtures in order to map the radiative and nonradiative transition probabilities.
