五个新的完全氟化的酰基酚盐配体，它们是β-二酮的芳族类似物，通过“天线效应”提供了在类似于1540 nm（对电信感兴趣）处的Er 3 + 4 I 13/2 -> I-4（15/2）发射的可见光敏化，如在Cs[ErL 4]化合物中观察到的。根据化学官能化，激发波长可以在400-650 nm范围内调谐。固体的衰变时间在7-16 μ s的范围内，证明复合物可以用于许多光电和光子应用。
Five new fully fluorinated acylphenoxide ligands, which are aromatic analogues of beta-diketonates, provide visible photosensitization of the Er3+4I13/2 -> I-4(15/2) emission at similar to 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 mu s, proving that the complexes can be of interest for a number of optoelectronic and photonic applications.
