Photoluminescent, lanthanide-containing, organic-inorganic hybrid materials find applications in various fields, such as: fluorescent biology, fluoroimmunoassays, NIR-emitting probes and amplifiers for optical communications.
In this NJC article, Ji-Na Hao and Bing Yan (Tongji University, Shanghai) report the preparation of new polymer thin films co-doped with lanthanide complexes and zeolite A. The lanthanide complexes are embedded into the cages of the zeolite, leading to host–guest materials with markedly enhanced thermal- and photo-stabilities.
All the materials are transparent and maintain the luminescent properties that are characteristic of lanthanide materials, emitting light with tuneable colours depending on the lanthanide used.
