Abstract
The emission intensities of Tb(hexafluoroacetylacetonato)3(H2O)2 [Tb(HFA)3(H2O)2] and Tb(HFA)3(triphenylphosphine oxide)2 [Tb(HFA)3(TPPO)2] in acetone-d6 dramatically decreased with increasing temperature in contrast to no change observed for Tb(NO3)3. The high thermal sensitivity is attributed to the back energy transfer from Tb(III) ion to triplet state of HFA having the energy barrier.Keywords
