A solution-based process utilizing dibenzophenone (DIBP) has been developed to create quantum dot (QD) patterns. UV exposure of DIBP generates ketyl radicals that interact with QDs. These cross-linked QDs remain solvent-resistant while preserving their optical properties. Photo patterning leverages UV-induced solubility differences, successfully achieving a 50 μm line pattern
