Novel perfluorodiphenylphosphinic acid lanthanide (Er or Er-Yb) complex with high NIR photoluminescence quantum yield.
A perfluorodiphenylphosphinic acid lanthanide (Er or Er-Yb) complex is synthesized by a one-pot process from perfluorotriphenylphosphine oxide and lanthanide (Er or Er-Yb) chloride; the photoluminescence quantum efficiency reaches 0.98% for the erbium complex and 3.5% for the erbium-ytterbium complex, about 50 times and 175 times, respectively, higher than the usual erbium organic complexes with the hydrogen-containing ligands.
