Overview Quantum dots (QDs) are semiconductor crystals that are several nanometers in size. Unlike bulk materials, changes in optical and electronic property occur at the nanoscale due to the quantum confinement effect and increased surface area. QDs exhibit this confinement effect and have the advantage of being able to control optical and electrical properties by scaling.
Technology Trend QDs have been widely used as a wide color gamut display material because it has easy wavelength control, high quantum efficiency, and a narrow FWHM (full width at half maximum) of the emission spectrum. In particular, QD TVs and monitors using QD films that convert blue LED light sources to red or green are now on the market. At present, we are actively developing and researching self-luminous QD-LED displays that utilize electroluminescence that converts electrical current into light, which can improve the viewing angle and contrast ratio of next generation displays. In QD applications, it is essential to synthesize high-quality, uniform QD materials to coordinate the QD surface with appropriate organic ligands. In addition to display materials, we are also investigating application to solar cells, photodetectors, biomarkers, photo catalysis, and other applications.
SAIT Technology SAIT has successfully developed eco-friendly QD materials for QLED TV and is currently conducting research on QD material and device interface technology for the next generation of QDs and self-luminous EL displays. Using nanomaterial technologies, we plan to continue to innovate new core materials for optoelectronic device and sensor applications.
