Abstract
The invention concerns an organic light-emitting diode comprising a lower electrode () and an upper electrode (), an electroluminescent organic layer (), and at least one doped organic layer () in contact with one of said electrodes. The invention is characterized in that the doping is carried out using an alkaline-earth element or lanthanide, and the diode is heat-treated at temperature preferably not less than 60° C. for more than one hour. The invention enables the lighting performance of the diode to be considerably improved.
