Synthesis of Quantum Dots

Abstract

Quantum Dots (QDs) are nano-sized semiconductor nanoparticles that are as small as a tenth of the width of a human hair. It has a good colour reproduction performance and reproduces natural colours, making it ideal for use in high dynamic range (HDR) displays, which are used in ultra-high definition displays. The fabric also boasts higher colour purity and photostability than existing luminescent materials, making it a promising new material for photoelectric devices such as next-generation screens. The color reproduction performance of QDs improves because the Full Width at Half-Maximum (FWHM) of the light-emitting wavelength of QD becomes smaller. Moreover, before the event of the proposed technology, the technical limit on the FWHM of Photoluminescent (PL) peaks for the green-emitting Cd-Free QDs was 35nm [1,2]. Quantum dot emitters (QDs) became common in wide color gamut LCD displays using quantum dot enhancement film. Several new display architectures using QDs also are under development. QDs have the potential to impact many various future display designs including LCD backlight units as is within the marketplace today; pixel-based color conversion of OLED, LCD, or micro-LED technologies; or as electroluminescent emitters in “OLED-like” displays. This chapter will describe the structure, benefits, and development status of every sort of QD display, including the challenges all faces relative to competitive technologies
