Quantum dot technology is revolutionizing the display and lighting industries, offering customizable color emission and enhanced brightness for high-quality visuals and energy-efficient illumination.
A quantum dot (QD) is an artificial semiconductor nanoparticle, typically ranging from 2 to 10 nanometers. At this scale, semiconductor particles exhibit quantum size effects, limiting the energy levels available to electrons and holes. This directly influences their optical properties, enabling precise tuning of color emission by controlling the QD size.
As a result, larger QDs emit longer wavelengths, such as red light, due to their larger band gaps, while smaller QDs emit shorter wavelengths, like blue light, owing to their smaller band gaps. This allows the production of high-quality, vibrant color displays and energy-efficient lighting solutions.
