Abstract
The new complexes of erbium and ytterbium with amine, phosphate and phosphine oxide ligands Ln(NH2R)3Cl3, Ln[O=P(NMe2)2NHR]3Cl3, Ln[O=P(OPh)2NHR]3Cl3, [R=CH2CH2CH2Si(OEt)3], Ln[O=P(OPh)3]3Cl3, Ln[O=P(CH2CH2CF3)3]3Cl3 and Ln[O=P(CH=CHPh)3]3Cl3 have been synthesised, and their absorption spectra have been measured in both films and solutions.
