High performance Ga N-based hybrid white micro-LEDs integrated with quantum-dots

Hybrid white micro-pillar structure light emitting diodes（LEDs） have been manufacture utilizing blue micro-LEDs arrays integrated with 580 nm CIS(（CuInS2-Zn S）/Zn S) core/shell quantum dots. The fabricated hybrid white micro-LEDs have good electrical properties, which are manifested in relatively low turn-on voltage and reverse leakage current. High-quality hybrid white light emission has been demonstrated by the hybrid white micro-LEDs after a systemic optimization, in which the corresponding color coordinates are calculated to be（0.3303, 0.3501） and the calculated color temperature is 5596 K. This result indicates an effective way to achieve high-performance white LEDs and shows great promise in a large range of applications in the future including micro-displays, bioinstrumentation and visible light communication.
