Low power upconversion using MLCT sensitizers
Radiy R. Islangulov, Denis V. Kozlov and Felix N. Castellano
Selective low energy excitation of the metal-to-ligand charge transfer (MLCT) transition in [Ru(dmb)3]2+(dmb = 4,4
-dimethyl-2,2-bipyridine) in the presence of anthracene or 9,10-diphenylanthracene yields easily visualized upconverted singlet fluorescence resulting from triplet–triplet annihilation at low excitation power.
