Fig. 5: Temperature-dependent emission lifetimes.

Temperature-dependent Tb(III) emission lifetimes (λex = 360 nm, λem = 542 nm) of [Tb2(hfa)6(dptp)2] in 2-MeTHF (0.5 mM, green dots) and Tb-NdMeTHF (0.5 mM, black and red dots). The solid lines are obtained by fitting with the Mott-Seitz model (Eq. 1). Error bar represents standard deviation.
