Title: POLYMER AND ELECTROLUMINESCENT DEVICE
Abstract:
An electroluminescent device includes an anode, a cathode, a light emitting layer between the anode and the cathode, and a hole transport layer between the anode and the light emitting layer. The light emitting layer includes an inorganic light emitting nanomaterial, and the hole transport layer includes an organic hole transport material. The organic hole transport material has HOMOHTM ≤ -5.4 eV and |(HOMO-1)HTM-HOMOHTM|≥ 0.3 eV.
