Upconversion materials have led to breakthrough applications in solar energy conversion, imaging, and biomedicine. Surprisingly, the best UC performances were obtained for Yb/Tb ratios close to parity.
Upconversion materials have led to various breakthrough applications in solar energy conversion, imaging, and biomedicine. One key impediment is the facilitation of such processes at the molecular scale in solution where quenching effects are much more pronounced. In this work, molecular solution-state cooperative luminescence (CL) upconversion arising from a Yb excited state is explored and the mechanistic origin behind cooperative sensitisation (CS) upconversion in Yb/Tb systems is investigated. Counterintuitively, the best UC performances were obtained for Yb/Tb ratios close to parity, resulting in the brightest molecular upconversion complexes with a quantum yield of 2.8x10(-6) at a low laser power density of 2.86 W cm(-2).
