Luminescent Eu(III)-based Coordination Polymers for Photonic Materials

Abstract

Abstract Eu(III) coordination polymers show red luminescence based on the 4f-4f transitions. The emission spectra are observed by excitation at a π–π* transition band of organic ligands in coordination polymers. The characteristic luminescence is dependent on their coordination geometry, vibrational structures and energy levels of organic ligands. In this review, their photophysical properties are introduced for future photonic materials.
