@@@@Colloidal semiconductor quantum dots based light-emitting diodes (QD-LEDs) have the advantages of high stability, solution processability, tunable emission wavelength and high color saturation, which have attracted great attention for applications in solid state lighting, flat panel display, and infrared communication. In this review, we first describe the advantages of using colloidal quantum dots (QDs) in LEDs and the light generation principle in QD-LEDs. Then we proceed to review the recent techno-logical advances of colloidal QD-LEDs based on three main groups of QDs: Group II-VI QDs (CdSe, CdTe, PbS, and PbSe), heavy metal-free Group III-V (InAs, InP) and Group I-III-VI QDs (CuInS, CuInSe), especially focusing on CdSe/CdS based QD-LEDs with various types of device components, structures and fabrication techniques. We conclude by addressing the key challenges and perspectives for the colloidal QD-LED technologies.
