稀土发光已成为生物分析研究或功能材料科学等现代光子学应用的重要支柱。然而，到目前为止，尽管稀土元素中具有最有趣的光物理特性之一，但在与有机增敏剂配体的分子络合物中，Tu的发光效率极低。这极大地阻碍了溶液中Tu发射的研究和应用。在这里，我们发现了一种有效的稀土光致发光增敏剂。相应的配合物具有发射效率(量子产率Φ>；0.12%；寿命τObs=4.6μS；亮度εΦ>；30M(-1)cm(-1))，甚至可以在低微摩尔浓度的水等高声子溶剂中检测到，而不需要激光激发。
Lanthanoid luminescence has become an important pillar for many modern photonics applications such as bioanalytical research or functional material science. So far, however, thulium despite having one of the most interesting photophysics among the lanthanoids has suffered from extremely low luminescence efficiencies in molecular complexes with organic sensitizer ligands. This has greatly hampered the investigation and application of thulium emission in solution. Here, the discovery of a powerful sensitizer for thulium photoluminescence is reported. The corresponding thulium complex exhibits emission efficiencies (quantum yield Φ > 0.12%; lifetime τobs = 4.6 μs; brightness εΦ > 30 M(-1) cm(-1)) and can even be detected at low micromolar concentrations in high-phonon solvents like water without the need for laser excitation.
