在基于三重态-三重态湮灭的光子上转换（TTA-UC）中，波长大于850 nm的近红外（NIR）光的利用仍然是一个突出的问题。我们通过使用金属酞菁作为三重致敏剂实现了这一点；在近红外光（856 nm）激发下，在可见光范围内观察到上转换发射，具有良好的光稳定性。
In triplet-triplet annihilation-based photon upconversion (TTA-UC), the utilization of near-infrared (NIR) light with a wavelength longer than 850 nm remains an outstanding issue. We realized this by employing metallonaphthalocyanines as triplet sensitizers; upon excitation of NIR light (856 nm), upconverted emission was observed in the visible range with remarkable photostability.
