一种席夫碱类稀土配合物的合成及荧光性质研究
Journal: Project Engineering DOI: 10.12238/pe.v3i3.13594
Abstract
稀土配合物因其独特的窄带发射、长荧光寿命及高色纯度等光学特性,在发光材料领域具有重要应用价值。本文以邻香兰素与氮位-甲基-2,2`-二氨基二乙胺缩合制备席夫碱配体(H₂L),进而与稀土金属盐和过渡金属盐反应,成功合成三核配合物EuZn₂(L)₂(OAc)₂(OH),并通过单晶衍射、红外光谱(IR)、紫外-可见吸收光谱(UV-Vis)、热重分析(TGA)及荧光光谱等手段对其结构及性能进行系统表征。该配合物具有良好的稳定性且荧光寿命达到微秒级别。本研究为设计高效稀土发光材料提供了新思路,所合成的配合物在显示器件与荧光传感等领域展现出潜在应用前景。
