摘要

用分辨率为1 μm的共聚焦光学显微镜研究了由非等距的β-二酮酸铕络合物熔粉制备的玻璃化膜的空间非均质性。结果表明，薄膜非晶结构中晶体夹杂物的非均质性导致薄膜在相同温度下可以处于不同状态，从而产生温度记忆效应。

Structural Features and the Effect of Temperature Memory in a Vitrivied Film of an Europium(III) β-Diketonate Complex

Confocal optical microscopy data with a resolution of 1 μm on the spatial heterogeneity of a vitrified film prepared from a melt powder of an anisometric europium(III) β-diketonate complex are presented. It has been shown that the heterogeneity caused by crystalline inclusions in the amorphous structure of the film, leads to a temperature memory effect, when the film can be in different states at the same temperature.
