Keywords:rare earth, thin film

In this talk, we will introduce the Terbium Complexes with two kinds of ligands, Hexafluoroacetylacetone and Maleimide, and the luminescent thin films of rare earths formed by electrostatic spraying. The terbium complexes were prepared by using two types of ligands to remove water molecules from the coordination sphere, which can lead to deactivation, and the luminescence intensity of the complexes was increased. By dissolving the complex in ethanol and using the electrostatic spraying method, we were able to successfully fabricate thin films in a solution process.
