Quantum Dots in Optoelectronics: Recent Trends and Future Perspectives

Abstract

Quantum dots (QDs) are semiconductor nanocrystals with unique optical properties due to quantum confinement effects. These properties, such as size-tunable emission wavelengths, high photostability, and quantum efficiency, have positioned QDs as key players in optoelectronic applications. This article discusses the recent advances in quantum dot technologies, focusing on their role in optoelectronic devices such as light-emitting diodes (LEDs), solar cells, photodetectors, and displays. Moreover, the article delves into the challenges faced in scaling quantum dot applications and outlines potential future developments in this field, emphasizing the integration of QDs in next-generation optoelectronics.
