We studied luminescent properties of two Nd 3+ complexes with two different ligands. The
first one was 1, 3-diketone bearing a pyrazole fragment and the second ligand was either 1,
10-phenanthroline or EtOH. For the ligand environment composed of 1, 3-diketone and 1, 10-
phenanthroline the position of the hybrid triplet level was as low as 18200 cm− 1. The
spectral features specific to Nd 3+ emission observed in the photoluminescence spectra of
the complexes under optical excitation provided the evidence for ion-centered …

We studied luminescent properties of two Nd 3+ complexes with two different ligands. The first one was 1, 3-diketone bearing a pyrazole fragment and the second ligand was either 1, 10-phenanthroline or EtOH. For the ligand environment composed of 1, 3-diketone and 1, 10-phenanthroline the position of the hybrid triplet level was as low as 18200 cm− 1. The spectral features specific to Nd 3+ emission observed in the photoluminescence spectra of the complexes under optical excitation provided the evidence for ion-centered luminescence. Radiative transitions were identified using the obtained spectroscopic data. Corresponding diagram of the energy levels of the complex with 1, 10-phenanthroline ligand was developed. Possible energy transfer pathways were discussed.
