✦ Synopsis

Tris-(hexafluoroacetylacetonato)neodymium(III), [Nd(HFA-D)3], was prepared by chelation of Nd 3+ ion with deuterated hexafluoroacetylacetone in CD3OD. Luminescence of the Nd 3 + complex was observed for the first time in organic solvents and the quantum yield was estimated to be of the order of 10 -2 in deuterated acetone solution. The absorption spectrum of [Nd(HFA-D) 3] dissolved in acetone was comparable with that of Nd 3+ ion in Y3A15015 matrix (Nd:YAG). Splitting of the 4F3/2 level was determined to be 82.3 cm-l in this system. These spectral characteristics suggest that the physical nature of Nd ~+ coordination environments should be uniform and well defined by coordination of HFA in solution.
