Abstract

A series of neodymium complexes with various modified β-diketonates and their corresponding gadolinium complexes have been synthesized and characterized. The singlet and triplet energy levels of the coordinated ligands were measured and compared. These complexes emit characteristic Nd3+ light at about 880, 1060, 1330 nm with long-lived lifetimes. The relationship between the structure and photophysical properties has been discussed and the energy transfer process in these complexes has been studied.
