We report the first observation of three photon induced NIR emission (890-1,400 nm) with NIR excitation (800 nm) from a newly synthesized organic neodymium complex with known molecular structure, suggests the potential use of lanthanide probes for use in three-dimensional imaging and further the study of multi- photon induced emission process in organic-lanthanide complexes.
