Abstract

Perdeuterated hexaflouroacetyIacetonato-ytterbium $[Yb(HFA-D)_3]$ complexes were synthesized by the keto-en01 tautomerism reaction of $Yb(HFA-D)_3$ in methanol-$d_4$ in order to reduce the radiationless transition to the ligands. The luminescence properties of $Yb(HFA-D)_3$ complex were measured in the following anhydrous deuterated organic solvents ; Acetone-$d_6$, Methanol -$d_4$, THF-$d_6$, PO$(OHC_3)_3$ and DMSO-$d_6$. The intensity, lifetime and quantum efficiency of the luminescence in DMSO-$d_6$ were superior to those in other deuterated solvents. It was suggested that the anhydrous DMSO-$d_6$ might be the most appropriate solvent for the liquid laser material of $Yb(HFA-D)_3$ complex.
