Researchers design a new method to deposit highly efficent QD-based emitters

A research team from POSTECH in Korea developed a new method of arranging quantum dots based on the coffee ring effect. The researchers dispersed the QD particles in a solution, and then evaporated it to perform the deposition, which causes the particles to automatically assemble in certain areas, like the edges of a single solution drop.

The researchers report that the QDs self-arranged in the form of very fine pixels, as they used a V-shaped structure. The QDs are driven toward the inner tips of the V-shape and accumulate there. This enables the creation of QD-based pixels that are 20 times brighter compared to regular QDs deposited without the V-shaped structure, and have a high uniformity rate of over 98%.
