| 摘要: 合成和鉴别了Nd3+、Er3+与谷氨酸(Glu)、天冬氨酸(Asp)形成的四个新的配合物,其组成为Ln4Glu11ClO4·8H2O、Ln4Asp11ClO4·8H2O(Ln=Nd、Er),其中配体通过羧基的氧原子与镧系离子配位。并通过配合物的水溶液的f-f光谱,计算了能级、成键和强度等参数。 |

| Abstract: Four novel Nd3+ and Er3+ complexes with aspartic acid and glutamic acid have been synthesized and characterized. Their composition are Ln4Glu11ClO4·8H2O、Ln4Asp11ClO4·8H2O(Ln = Nd, Er). In these complexes artiino acid connect the Ln ions through the oxygen atoms of carboxyl groups. Absorption spectra of solution state in range 900-330 nm have been analyzed to calculate Slater-Condon, Lande, nephelauxetic effect and Judd-Ofelt intensity parameters. |
