Patent number: 7977672Abstract: A two-terminal organic light-emitting device structure is presented with low absorption losses and high current densities. Light generation and emission occur at a predetermined distance from any metallic contact, thereby reducing optical absorption losses. High current densities and thus high emitted light intensity are achieved by combining two types of conduction in one device: by combining space charge limited conduction and field-effect conduction or by combining ohmic conduction and field-effect conduction, thereby optimizing the current densities. This results in a very high local concentration of excitons and therefore a high light intensity, which can be important for applications such as organic lasers, and more in particular electrically pumped organic lasers.Type: GrantFiled: May 27, 2010Date of Patent: July 12, 2011Assignees: IMEC, Katholieke Universiteit LeuvenInventors: Sarah Schols, Stijn Verlaak, Paul Heremans
