Zusammenfassung: | The invention relates to an electroluminescent material and a non-doped electroluminescent device made of the electroluminescent material. The electroluminescent device comprises a cathode, an anode and a luminescent layer located between the cathode and the anode, and the luminescent layer is composed of a luminescent d-f transition Ce (III) complex or Eu (II) complex. The luminescent d-f transition Ce (III) complexes have one or more Ce < 3 + > ions as central luminescent ions and ligands that form coordination bonds with the Ce < 3 + > ions, and the first coordination layer around these Ce < 3 + > ions has 3 to 15 coordination atoms, including one or more of C, N, O, F, Cl, Br, I. The non-doped device has better electroluminescent performance than a same doped device, and meanwhile, the manufacturing cost is lower.
