稀土配合物杂化发光材料的组装及光物理性质研究进展

Abstract

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. The research results of this review might have theoretical significance for the potential applications of the rare earth luminescent materials in the fields of lighting devices (light-emitting diodes, optical fibers, optical amplifiers, lasers) and biomedical analysis.
