We developed quantum dot (QD) based color-conversion white LEDs that reach over 150 lumens per electrical Watt. For that we synthesized alloyed ZnCdSe/ZnSe QDs with 94% of quantum efficiency and injected QD-liquids on blue LEDs.

We demonstrate efficient white LEDs by using the combination of green-emitting near-unity quantum dots with red-emitting nanorods. Stokes-shift in red via dot-to-rod transition reduced absorption losses and led to a high quantum efficiency of 42.9%.
