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.
