摘要

X-Ray photoelectron and luminescence spectroscopy was used for studying heteroligand compounds of neodymium(III) with either trifluoroacetic or cinnamic acid as well as nitrogen- and phosphorus-containing neutral ligands. Tendencies toward increased electron density on the neodymium ion and enhanced relative intensity of the band for the 4F3/2–4I11/2 transition are seen upon coordination of the neutral ligands by means of the donor nitrogen atom in similar groups of compounds. The strongest luminescence was found for the complex of neodymium(III) cinnamate with 1,10-pheanthroline.
