摘要：

The synergetic effect on the efficiency of triplet-triplet-annihilation- assisted photon upconversion, as a result of a synthetic procedure for simultaneous and independent optimization of the intrinsic efficiencies of triplet-triplet transfer and triplet-triplet annihilation, is demonstrated (see picture). The new system shows high upconversion quantum yields of order of 0.11. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
