Quantum Dots in Light Emitting Diode and Their Applications

The development of confined dimensionality in nanoscopic materials has paved the path for many promising applications for human societies. One aspect is zero-dimensional quantum dots (QD) synthesized by various methods. These QDs have a significant role in technological advancements of various healthcare and environmental applications. In this current section, methodologies involved in fabricating quantum dot light emitting diode (QLED) are discussed. The phenomenon of emitting light from provided electrical energy is termed electroluminescence (EL). The mechanisms involved in obtaining electroluminescence are vital to build a working understanding. Three major mechanisms namely, energy transfer, field inducing, charge injection is prominently discussed in the coming sections. Furthermore, the advancements made in developing QLEDs are of huge interest, detailed of type I, II, and III structures are provided. Eventually the day-to-day modern applications of QLEDs in data communication technologies, sensor technologies, and data display technologies are covered with wider information range.
