Аннотация:New NIR emitting materials were found among the lanthaninde complexes with 2-(tosylamino)benzylidene-N-benzoylhydrazone. Complexes of Nd3+, Er3+ and Yb3+, as well as Eu3+, Gd3+ and Lu3+, were synthesized for the first time. Thanks to the absence of the vibration quenching ytterbium complex was found to exhibit the photoluminescence quantum yield of 1.4%. Since sensibilization efficiency was calculated to be 55%, the losses in the quantum yield are probably due to Yb-Yb resonant energy transfer.
