Abstract
In recent times, quantum dots (QDs) have gained enormous consideration for their exceptional characteristics in display devices (LCD) and light-emitting diode (LED) applications with polymer-based composite nanomaterials to enhance the strength of the properties. Because of their excellent optical, thermal, electrical, photonic, physical, and mechanical properties, with their tremendous stability and suitable wavelength. Further, with their adaptability to oxygen, water, illumination, and heat, quantum dots using polymer nanocomposites have been widely produced and used in LEDs, photovoltaics, photodetectors, and display devices. The synthesis of these nanocomposite materials in optoelectronics, photodetectors, solar cells, photonics, and photosensors has been remarkable in quantum dot technology. In the area of applied nanomaterial research investigation, the QDs have remained an active and intense platform. This chapter discusses how to improve polymer-based composite quantum dots, evolution, the role of QDs, challenges, recent advancements, and applications. The wide range of applications for QD-polymer composites in lighting and display are also discussed.
