We report white light generation by hybridizing green-red emitting (CdSe)ZnSCdSe (core)shell/shell quantum-dot-quantum-well heteronanocrystals on blue InGaNGaN light emitting diodes with the photometric properties of tristimulus coordinates (x,y)=(0.36,0.30), luminous efficacy of optical radiation LE=278lmW, correlated color temperature CCT=3929K, and color-rendering index CRI=75.1. We present the photometric analysis and the quantum mechanical design of these dual-color emitting heteronanocrystals synthesized to achieve high-quality white light when hybridized on light emitting diodes. Using such multicolor emitting heteronanocrystals facilitates simple device implementation while providing good photometric properties.
