However, a major challenge is achieving ultrahigh-resolution patterning without damaging their fragile surface chemistry. Existing methods such as inkjet printing and photolithography-based processes either fall short in resolution or compromise QD performance.<\/p>\n<p>To address this, a research team led by Associate Professor Jeongkyun Roh from the Department of Electrical Engineering, Pusan National University, Republic of Korea, has introduced a universal, photoresist-free, and nondestructive direct photolithography method for QD patterning. Instead of exposing QDs to harsh chemical modifications, the team engineered a photocrosslinkable blended emissive layer (b-EML).<\/p>\n<p>This layer is formed by mixing QDs with a hole-transport polymer and a small fraction of an ultraviolet (UV)-activated crosslinker, enabling precise patterning while preserving QD integrity.
