Molecular thin films that are periodically layered and core–shell type nanoparticles with interfacial coordination are observed in lanthanide complexes via organic photo-antennae. The layer structures of Eu complexes induced the linearly polarized luminescence (LPL) of ff-transitions by using the Langmuir-Blodgett technique. The aforementioned was achieved due to the independent existence of Eu and the interpretation of the transition dipole moment localized on chromophores in the layers. The chain structure of the complexes was sequentially deposited on the substrates, but exhibited no LPL due to the formation of dome-like chain aggregates. The interfacial coordination can adopt various combinations of nanoparticles (e.g., SiO₂, TiO₂, and Ln₂O₃) with different lanthanides and various types of organic shells to induce upconversion even with low-power light or efficient photomultiplying photodetection. The divalent Eu ion demonstrated high stability.

通过有机光天线在镧系元素络合物中观察到周期性分层的分子薄膜和具有界面配位的核-壳型纳米颗粒。Eu复合物的层结构通过使用Langmuir-Blodgett技术诱导ff跃迁的线性偏振发光（LPL）。前述的实现是由于Eu的独立存在以及对过渡偶极矩在层中生色团上的解释。复合物的链结构顺序沉积在基底上，但由于形成圆顶状链聚集体而没有LPL。界面配位可以采用纳米颗粒的各种组合（例如，SiO ₂，TiO ₂和Ln ₂ O ₃），即使使用低功率光或有效的光电倍增光电检测，也可以使用不同的镧系元素和各种类型的有机壳来诱导上转换。二价Eu离子显示出高稳定性。
