Invited Paper. Quantum Dots as a new generation of emitting materials in OLEDs
Abstract
Colloidal quantum dots (QDs)-based light-emitting diodes (QD-LEDs) has been actively researched due to the potential impacts to the display and lighting industry base on the unique properties of QDs itself such as size-dependent bandgap tuneability, narrow emission spectrum, and low-cost solution-based processing. However, the most of promising results in the past used cadmium (Cd) contained II-VI semiconductor nanocrystals. Therefore, a considerable future task is to substitute Cd-containing QDs with less toxic materials. InP-based QDs is a promising material among the III-V semiconductor nanocrystals and it has been already applied in conventional and inverted QD-LED structure.
