Luminescent materials enable warm white LEDs, molecular tagging, enhanced optoelectronics and can improve energy harvesting. With the recent development of multi-step processes like down- and upconversion and the difficulty in sensitizing these, it is clear that optimizing all properties simultaneously is not possible within a single material class. In this work, we have utilized the layer-by-layer approach of atomic layer deposition to combine broad absorption from an aromatic molecule with the high emission yields of crystalline multi-layer lanthanide fluorides in a single-step nanocomposite process. This approach results in complete energy transfer from the organic molecule while providing inorganic fluoride-like lanthanide luminescence. Sm³⁺ is easily quenched by organic sensitizers, but in our case we obtain strong fluoride-like Sm³⁺ emission sensitized by strong UV absorption of terephthalic acid. This design allows combinations of otherwise incompatible species, both with respect to normally incompatible synthesis requirements and in controlling energy transfer and quenching routes.

发光材料可实现暖白光 LED、分子标记、增强光电子学，并可改善能量收集。随着最近开发的多步过程（如下转换和上转换）以及对这些过程敏感的困难，很明显在单一材料类别中同时优化所有属性是不可能的。在这项工作中，我们利用原子层沉积的逐层方法，在单步纳米复合工艺中将芳香族分子的广泛吸收与结晶多层镧系元素氟化物的高发射产率相结合。这种方法导致有机分子的能量完全转移，同时提供无机氟化物类镧系元素发光。SM ³⁺很容易被有机敏化剂淬灭，但在我们的例子中，我们获得了由对苯二甲酸的强紫外线吸收敏化的强氟化物 Sm ^3+发射。这种设计允许组合其他不相容的物质，既涉及通常不相容的合成要求，也涉及控制能量转移和淬火路线。
