摘　　要：采用回流冷凝法合成了近红外发光的YbAA(TTA)2phen配合物,对配合物进行的荧光光谱分析结果表明:配合物中Yb3+的2F5/2→2F7/2电子跃迁被分成了3个峰。采用原位反应方法制备了键合型的YbAA(TTA)2phen/EVA复合材料,对复合材料进行的SEM,XRD分析结果表明:交联固化后配合物在复合材料中分散性增强,颗粒变小。对YbAA(TTA)2phen/EVA复合材料进行的荧光光谱分析结果表明:复合材料表现为Yb3+的特征发射,且相同配合物含量下交联固化后的复合材料的发光强度要强得多。对YbAA(TTA)2phen/EVA复合材料进行了拉伸性能和原子力显微镜表征,结果表明:交联固化后复合材料的拉伸强度和平整度得到了提高。Near-infrared luminescent YbAA （rlTA） 2phen complex was obtained in reflux and condensation method. Its Fluorescent spectra showed that the 2F5/2→2F7/2 transitions of the Yb^3＋ ions were split into three bands. The YbAA （TTA）2phen/EVA composites were synthesized by in-situ method. The SEM and XRD analysis showed that the particles of YbAA （TTA） 2phen complex in cured composite material be-came smaller and more dispersive. In the photoluminescence studies, the composites showed NIR luminescence of Yb^3＋ ions, and the cured composite materials had larger luminescent intensity than uncured ones. The mechanical properties and AFM of the composites indicated that the composites had better tensile strength and flatness after crosslinking and curing.
