“…This transfer was observed directly through transient absorption spectroscopy of a liquid mixture of the optically active molecules. The rate of this energy transfer varied with relative concentration in the same manner as predicted by the rate model developed by J. Auckett et al [3].…”

“…This finding has been further corroborated by Schmidt and coworkers. 45 Very recently, Haefele et al have shown that rigorously removing oxygen -a well known triplet quencherfrom the UC system allows one to shift the transition from the linear regime -where the quantum efficiency is maximal -to the quadratic regime towards much lower power densities than hitherto reported. 54 This has allowed them to access the linear regime when exciting a solution of PdOEP and DPA in toluene with non-coherent light of a power density of a few mW cm À2 .…”

“…However, there are several critical properties of these systems that must be optimized for this technology to be viable for incorporation into real-world applications. First, because the photon UC via sensitized TTA process occurs through diffusional, bimolecular chemistry, the measurement and improvement of the quantum efficiency in these systems becomes crucial [20,22,35,46]. Second, in order to reap the greatest benefits from these compositions, it is necessary to maximize the anti-Stokes shift that can be achieved.…”
