"Increased color conversion efficiency in hybrid light emitting diodes utilizing non-radiative energy transfer"

Advanced Materials 22, (5) 602 (2010)

Abstract: An efficient hybrid color-conversion light-emitting device consisting of colloidal nanocrystal quantum dots (NQDs) and a surface-patterned GaN-based LED is demonstrated (see figure). Excitation in a surface-patterned LED is efficiently transferred to NQD emitters via non-radiative energy transfer. A twofold enhancement of the NQD emission is achieved.
