三-(六氟乙酰丙酮)钕[Nd(HFA-D)(3)]是通过Nd3+离子与氘代六氟乙酰丙酮在CD3OD中螯合而制备的。首次在有机溶剂中观察到Nd3+配合物的发光，并且在氘代丙酮溶液中估计量子产率为10(-2)量级。溶解在丙酮中的[Nd(HFA-D)(3)]的吸收光谱与Y3Al5O15基质(Nd:YAG)中Nd3+离子的吸收光谱相当。该系统中F-4(3/2)水平的分裂被确定为82.3 cm(-1)。这些光谱特征表明 Nd3+ 配位环境的物理性质应该是均匀的，并且由溶液中 HFA 的配位明确定义。
Tris-(hexafluoroacetylacetonato)neodymium [Nd(HFA-D)(3)], was prepared by chelation of Nd3+ ion with deuterated hexafluoroacetylacetone in CD3OD. Luminescence of the Nd3+ 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 Nd3+ ion in Y3Al5O15 matrix (Nd:YAG). Splitting of the F-4(3/2) level was determined to be 82.3 cm(-1) in this system. These spectral characteristics suggest that the physical nature of Nd3+ coordination environments should be uniform and well defined by coordination of HFA in solution.
