In this paper,hypersensitive transitions of Nd(Ⅲ)in Nd(Ⅲ)-β-diketone-neutralligand ternary coordination compounds(where β-diketone=acetylacetone(AA),benzoylace-tone(BA),dibenzoylmethane(DBM),2-thenoyl trifluoroacetone(TTA);neutral ligand=pyri-dine(Py),α,α’-dipyridyl(Dipy),phenanthroline(Phen)are studied and their intensitiesare given through dynamic coupling model.The results are in agreement with those observedand caleulated using Judd-Ofelt equation.It may be seen that the dynamic couplingmechanism provides major contribution to the intensity of hypersensitive transition.On theother hand,in order to get the intensity of ~4I_(9/2)→~4G_(5/2) transition,the absorption spectra in560—610 nm have been decomposed into threo peaks by nonlinear fitting with Lorentzian andGaussian funetion and the“pure”intensities of hypersensitive transitions have been obtained,which are agreeable to those computed by Judd-Ofelt method and dynamic coupling model.
In this paper, hypersensitive transitions of Nd (Ⅲ) in Nd (Ⅲ) -β-diketone-neutralligand ternary coordination compounds (where β-diketone = acetylacetone (AA) (TTA); neutral ligand = pyri-dine (Py), α, α’-dipyridyl (Dipy), phenanthroline (Phen) are studied and their intensitiesare given through dynamic coupling model. The results are in agreement with those observed and caleulated using Judd-Ofelt equation. It may be seen that the dynamic coupling mechanism provides major contribution to the intensity of hypersensitive transition. On theother hand, in order to get the intensity of ~4I_ (9/2) → ~ 4G_ (5/2) transition, the absorption spectra in 560-610 nm have been decomposed into threo peaks by nonlinear fitting with Lorentzian and Gaussian funetion and the “pure” intensities of hypersensitive transitions have been obtained, which are agreeable to those computed by Judd-Ofelt method and dynamic coupling model .
