To achieve FRET enhancement at 614 nm, we use an energy gradient hybrid structure made of cyan- and orange-emitting CdSe/ZnS NCs (λPL =492 and 588 nm in solution, respectively). This enables recycling of trapped excitons using FRET and achieves a relative quantum efficiency enhancement of 15.1% in reddish-orange full color-conversion for the integrated hybrid cyan-orange NC layer with respect to the case of full color-conversion using only orange NCs without FRET.EnglishCdSe/ZnSColloidal semiconductorsEnergy gradientsFull colorHybrid structureQuantum dotResonance energy transferSolid state lightingTrapped excitonColorEnergy transferLight emitting diodesLightingOptical waveguidesResonanceSemiconductor diodesSemiconductor quantum dotsArticle10.1063/1.3222902
