ABSTRACT:
An electroluminescent device comprising a composite structure including first and second electrodes, first and second electroluminescent layers between said electrodes, and an electrically-insulating layer between and contacting both of the electroluminescent layers, said electrically-insulating layer having a substantially-uniform thickness in a range that permits substantial tunnelling of electrons therethrough when as little as 10 to 30 volts are applied across said electrodes.
