Abstract

The optical properties of three Sm(III)-beta-diketonate complexes with different neutral ligands in methyl methacrylate have been investigated and the influence of the neutral ligand on fluorescence emission, Judd-Ofelt intensity parameters and metastable state lifetime was analyzed. The eta intensity parameters and Judd-Ofelt intensity parameters were obtained from fluorescence emission spectra and absorption spectra, respectively. The metastable state lifetime measurements correspond with the results obtained from fluorescence emission spectra and absorption spectra.

摘要

研究了三种含有不同中性配体的Sm(III)-β-二酮配合物在甲基丙烯酸甲酯中的光学性质，并分析了中性配体对荧光发射、贾德-奥费尔特强度参数和亚稳态寿命的影响。分别从荧光发射光谱和吸收光谱中获得了η强度参数和贾德-奥费尔特强度参数。亚稳态寿命测量结果与从荧光发射光谱和吸收光谱中获得的结果一致。
