Polymer additives for improving the selective electrophoretic deposition morphology of quantum dots

Quantum dots (QDs) is widely used in the display field due to its excellent photoelectric properties and relatively good stability. The patterning of QD is an important part of solid state integration of high precision QDs optoelectronic devices. However, traditional patterning techniques either degrade material properties or have complex processes. In this study, selective electrophoretic deposition (SEPD) was used as a patterning strategy, and polymer additives were added to the QD ink to improve the deposition morphology and achieve efficient and non-destructive patterning.
