The invention discloses an infrared organic electroluminescent device. The device comprises a pair of electrodes and an organic luminescent dielectric layer arranged between the electrodes, wherein the organic luminescent dielectric layer at least comprises a luminescent layer and an electron transmission layer; the luminescent layer comprises a main body material and a guest body material; the hole mobility of the guest body material is between 10<-3> and 10<-6>cm<2>V<-1>s<-1>, and is more than 1 to 3 orders of magnitude more than the electron mobility; the electron transmission layer is formed by the electron transmission material, the hole mobility of the electron transmission material is more than or equal to 10<-4>cm<2>V<-1>s<-1>; and the energy gap (Eg) of the guest body material is between 2.18 and 1.59eV. The organic electroluminescent device has the advantages of high efficiency, excellent chromaticity and long service life.
