Ligand-centered near-infrared luminescence from lanthanide complexes with chelating nitronyl nitroxide free radicals
Lanthanum(III), europium(III), and gadolinium(III) complexes with chelating nitronyl nitroxide free radicals show luminescence between 700 and 1000 nm. The resolved vibronic structure involves both radical-centered and metal-radical modes.
