We report white light generation by hybridizing green-red emitting (core)shell/shell quantum-dot-quantum-well heteronanocrystals on blue light emitting diodes with the photometric properties of tristimulus coordinates , luminous efficacy of optical radiation , correlated color temperature , and color-rendering index . 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.
