Abstract

The paper examines the effect of introducing a chlorine atom into the coordination sphere of a rare earth ion for two novel Eu3+ organometallic compounds. Using spectral and time-resolved measurements, we show that the introduction of a chlorine atom provides a way to achieve a significant increase (from 27 to 36%) in the luminescence efficiency of the studied compounds due to coordination symmetry breaking in the complexes.

引入氯对带有 β-二酮类和未成熟羧酸的新型 Eu3+ 配位化合物发光特性的影响
摘要 本文研究了在两种新型 Eu3+ 有机金属化合物的稀土离子配位层中引入一个氯原子的效果。通过光谱和时间分辨测量,我们发现引入一个氯原子可以使所研究化合物的发光效率显著提高(从 27% 提高到 36%),这是由于配合物中的配位对称性发生了破坏。
