文摘 稀土配合物兼具无机物稳定性好以及有机物荧光量子效率高的优点, 而且具有可设计性, 制备简便, 容易修饰, 荧光性质优异(发射谱带窄、色纯度高、荧光寿命长、量子产率高以及发射光谱范围覆盖可见和近红外光区等). 但配合物的光、热、化学稳定性和机械加工性能相对较差, 因而限制了其在很多领域中的实际应用. 近年来的研究表明, 将稀土配合物引入到各种基质材料中可以改善其稳定性及机械加工性能, 并对其光物理性质产生调制作用. 根据基质材料的不同, 杂化材料可分为无机基质、无机/有机复合基质及有机基质杂化材料. 本文综述了这些不同基质稀土配合物杂化发光材料的研究进展, 探讨了主客体间相互作用对杂化材料光物理性质及稳定性的影响, 为实现稀土配合物杂化发光材料在光学器件领域(LED照明、光纤维、光学放大器及激光等)及生命分析领域的应用提供了重要的理论依据.
其他语种文摘 The rare earth complexes have a few good features, which combine the good stabilities of inorganic component with high luminescence quantum efficiencies of organic component. Meanwhile, they can be designed and easy synthetized, and have excellent photoluminescent properties, such as sharp emission spectra for high color purity, broad emission bands covering the visible to near infrared region, a wide range of lifetimes, and high luminescence quantum efficiencies. However, the factors such as poor stabilities under high temperature or moisture conditions and low mechanical strength limit their practical use. In order to circumvent these drawbacks, rare earth complexes have been incorporated into the matrices to constitute hybrid materials. The solid matrices could be divided into inorganic, organic and inorganic/organic mixed matrices. Herein, the research progresses of different matrices based lanthanide hybrid materials have been reviewed. The effects of the host-guest interactions on the photophysical behaviors and stabilities of the hybrid materials have also been discussed.
