Abstract
The present disclosure provides an organic electroluminescent device comprising: a cathode; an anode; an N-type organic semiconductor between the cathode and the anode; and a P-type organic semiconductor between the N-type organic semiconductor and the anode and in contact with the N-type organic semiconductor, wherein the P-type organic semiconductor has a LUMO energy level between a LUMO energy level and a HOMO energy level of the N-type organic semiconductor, and an energy level difference between the LUMO energy level of the N-type organic semiconductor and the LUMO energy level of the P-type organic semiconductor corresponds to an electron transition luminescence spectral range in a wavelength range between near-infrared to ultraviolet.
