In situ synthesis, crystal structure and photophysical properties of a new binuclear europium compound

A novel europium complex was synthesized. It features a binuclear structure. A photoluminescence measurement with solid-state samples reveals that it can emit brown photoluminescence. It has CIE (Commission Internationale de I'Éclairage) chromaticity coordinates (0.557, 0.4292) and its CCT (Correlated Color Temperature) is 1871 K. The solid-state diffuse reflectance spectra reveals that it has a wide semiconducting bandgap of 4.09 eV.
