An electroluminescent device and a preparation method in which an electroluminescent device comprises an anode (102), a luminescent layer (104) and a cathode (106), and the luminescent layer (104) is located between the anode (102) and the cathode (106), wherein the luminescent layer (104) contains inorganic luminescent nanoscale materials and polyimide polymers, in which the HOMO of polyimide polymers and the non - polyimide polymers The valence band energy level VB of the luminescent nanomaterials satisfies the VB (inorganic light-emitting nanomaterials) less than HOMO (polyimide) +0.3eV, which provides a solution for high performance electroluminescent devices that are easily processed in large area. The invention also relates to an ink composition comprising nano luminescent materials and polyimide polymers.
