Single-component electroluminescent white light-emitting diodes based on zinc oxide quantum dots with high color rendition and tunable correlated color temperature

Single-component WLEDs with tunable CCT from 3303 to 8055 K and very high CRI >90 have been realized using ZnO-QDs as emissive layer, which opens up a new avenue for the development of low-cost, environment-friendly, and high-performance single-component WLEDs.
