제목 Environment Friendly Quantum-Dot Color Filters for UHD Liquid Cystal Displays
초록 Indium phosphide (Inp) quantum dots (QD) are considered an alternative to Cd-containing QDs for use in light emitting devices. It has been demostrated that multilayer shell coating with ZnSe / ZnS show stronger enhancement of the Quantum Yield (QY) of the InP quantum dot than the conventional ZnS shell coating. Multi-shells help reducing the lattice mismatch between the consecutive crystalline layers within the quantum dot and improves performance of the QDs. We have synthesized highly fluorescent ZnSe1-XSX gradient shell QDs to reduce lattice defects small. Green and Red QDs showed QY values in the range of 65% with an FWHM of 40-50 nm. The fabrication of QD-LED devices using green and red ZnSe1-XSX materials led to sharp emission with reduced overlap.
