Nanostructured Electroluminescent Device and Display
An electroluminescent device contains
(1) first and second electrodes, at least one of which is transparent to radiation;(2) a hole conducting layer containing first nano particles wherein the hole conducting layer is in contact with said first electrode; (3) an electron conducting layer containing second nanoparticles where the electron conducting layer is in contact with the hole conducting layer and the second electrode; and optionally(4) a voltage source capable of providing positive and negative voltage, where the positive pole of the voltage source is connected to the first electrode and the negative pole is connected to the second electrode. In some embodiments, the electroluminescent device also includes an electron-hole combination layer between the hole and electron conducting layers.
