Quantum dots (QDs) and nanoparticle (NPs) based light-emitting diodes (LEDs) demonstrate a platform of light-emitting technology and are considered a significant display technology for the next generation after the reach of organic light-emitting diodes (OLEDs) display. QDs and NPs-based LEDs are different from plasma displays, liquid crystal displays (LCDs), and OLEDs because of their unique properties, such as long life, low consumption of power, environmental safety, small size, low operating voltage, broad range of operating temperatures without substantial degradation, and a high CRI ratio (color rendering index). The various synthesis approaches, such as laser ablation, the arc discharge method, sputtering, solvothermal and hydrothermal methods, the hot-injection method, the heat-up method, microwave-assisted synthesis, sol–gel, the co-precipitation method, and the microemulsion method of QDs and NPs for light-emitting diodes and displays applications, have been explained broadly. However, there are still many existing difficulties that need to be improved and solved, like the optimized synthesis process, improved carrier transport, environmental compatibility, stability, and reliability for QD and NPs. The aim of this chapter is to demonstrate the historical background and synthesis approaches of QDs and NPs for LEDs and display applications. Moreover, we provide the most recent advancements and applications of QDs and NPs in this field.
