首次实现了基于三重态-三重态湮灭（TTA）的近红外光（λ> 700 nm）向紫光（λ < 450 nm）的上转换，方法是开发一种硅基取代的蒽紫发光体，并通过锇配合物对其进行敏化，该配合物在近红外光范围内显示出单重态-三重态（S-T）吸收。
Upconverting near-infrared (NIR) light (lambda> 700 nm) to violet light (lambda< 450 nm) based on triplet-triplet annihilation (TTA) is achieved for the first time by developing a silyl-substituted anthracene violet emitter and its sensitization by an osmium complex showing a singlet-to-triplet (S-T) absorption in the NIR range.
