Unraveling Quantum Dots

Abstract

Quantum dots represent a class of semiconductor nanocrystals with exceptional optical and electronic properties, stemming from their quantum confinement effects and size-tunable energy levels. This chapter provides a comprehensive exploration of quantum dots, beginning with a historical overview of their discovery and development. We delve into the synthesis methods employed to fabricate quantum dots, highlighting their influence on size, shape, and composition. Structural properties such as quantum confinement effects and surface chemistry considerations are elucidated to underscore their impact on quantum dot behavior.Furthermore, the chapter comprehensively examines different properties of quantum dots, including size-dependent emission spectra, high quantum yields, and applications in optoelectronic devices.Through this chapter, readers will gain a deep understanding of the underlying principles governing quantum dots and their transformative potential across scientific disciplines.
