In these proof-of-concept demonstrations, high color rendering indices (82.4) and high luminous efficacies of emitted spectra (327 lm/W) were achieved, while the color temperature was simultaneously kept low as desired. Our proof-of-concept demonstrations indicated that such nanocrystal luminophor based warm-white LEDs with high-quality photometric properties hold great promise especially for future indoor lighting applications.EnglishHybrid power systemsNanocrystalsLight emitting diodesTemperatureStimulated emissionOptical pumpingOptical sensorsLight sourcesPhosphorsZinc compoundsConference Paper10.1109/LEOS.2008.4688558
