CHAPTER 11.5: Nanoparticles and Quantum Dots Check Access

Quantum dots (QDs) are semiconductor nanoparticles smaller than their Bohr radius with excitons confined in three dimensions. Owing to their unique optical and electronical properties, QDs have become one of the most popular building blocks for nanoscience and nanotechnology and have been studied extensively during recent decades. In this chapter, we briefly overview the history of QDs research. Various synthetic methods of QDs are discussed in detail, especially aqueous‐phase routes for Group II–VI QDs. The progress of using QDs in light‐emitting diodes (LEDs) and solar cells is also mentioned.
