The fast degradation of blue QLED is the most challenging issue in QLED, and we found out the conduction band minimum offset between blue QDs and ZnO is the primary reason. Instead of optimizing ETL layer, we alternatively tailored QD core‐shell structure and achieved greatly enhanced lifetime of blue QLED.

Quantum dot light emitting diodes (QLEDs) as low-cost PDT light sources (Conference Presentation)
17th International Photodynamic Association World Congress, 2019Homogeneous, flexible light sources with pure, deep red color and sufficiently high power densities are necessary for more effective and widely used photodynamic therapy (PDT), but have been difficult to achieve with lasers or LED arrays at reasonably low cost.

Carrier injection and transport in the quantum dot (QD) layer was modulated by tuning the Schottky injection barrier and mobility of charge transport layers. The analyses indicate that stages of the J-V curve for hole injection must match with those of electron injection to achieve the charge balance in the QD layer.

Over the past years, QLEDs technology has experienced a huge development in aspects of fabrication process, device structure, QDs and CTLs materials, and patterning method. With the EQEs of RGB QLEDs based on cadmium compound II-VI QDs all exceeding 10 % and even approaching that of state-of-the-art phosphorescent OLEDs, QLEDs technology becomes a ...

Design of high performance indium phosphide (InP) - based quantum dot light emitting diodes (QLEDs)
2018This dissertation is dedicated to the development and understanding of fundamental device mechanism and engineering of the device architecture of quantum dot light-emitting diodes (QLEDs) based on indium phosphide (InP) quantum dots. QLEDs have emerged as a next-generation flat panel display (FPD) technology with promising properties.
