Visible-Range Sensitization of Er(3+)-Based Infrared Emission from Perfluorinated 2-Acylphenoxide Complexes

Abstract:
Five new fully fluorinated acylphenoxide ligands, which are aromatic analogues of β-diketonates, provide visible photosensitization of the Er(3+4)I13/2 → (4)I15/2 emission at ∼1540 nm (of interest for telecommunications) via the "antenna effect", as observed in Cs[ErL4] compounds. Depending on the chemical functionalization, the excitation wavelength can be tuned in the 400-650 nm range. Decay times for the solids are in the range of 7-16 μs, proving that the complexes can be of interest for a number of optoelectronic and photonic applications.
