Gallium nitride/conjugated polymer hybrid light emitting diodes: Performance and lifetime

We report on pure white light emission from GaN/conjugated polymer hybrid light emitting diodes (LEDs) using a single layer of conjugated polymer. When the conjugated polymer is properly encapsulated, the hybrid LEDs can operate at least 5000 h, with decay in output luminosity comparable to that of commercial blue GaN lamps. By using different conjugated polymers, emission with a full range of colors is demonstrated with the hybrid LED.
