dc.description.abstractWarm-white light emitting diodes with high color rendering indices are required for the widespread use of solid state lighting especially indoors. To meet these requirements, we propose and demonstrate warm-white hybrid light sources that incorporate the right color-converting combinations of CdSe/ZnS core-shell nanocrystals hybridized on InGaN/GaN LEDs for high color rendering index. Three sets of proof-of-concept devices are developed to generate high-quality warm-white light with (1) tristimulus coordinates (x,y)=(0.37,0.30), luminous efficacy (LE)=307 lm/W, color rending index (CR)=82.4, and correlated color temperature (CCT)=3228 K; (2) (x,y)=(0.38,0.31), LE=323 lm/W, CRI=81.0, and CCT=3190 K; and (3) (x,y)=(0.37,0.30), LE=303 lm/W, CRI=79.6, and CCT=1982 K.en_US
