Direct optical lithography presents a promising patterning method for colloidal quantum dots (QDs). However, additional care needs to be taken prevent deterioration of the properties QDs upon patterning, especially InP-based QDs. This study proposes an efficient high-resolution using photoacid generator while preserving their properties. Specifically, our solid-state ligand exchange strategy, replacing chloride ligands with long-chain amine/carboxylate pair ligands, successfully recovered...
We present a universal direct photocatalytic patterning method that can completely preserve the optical properties of perovskite nanocrystals (PeNCs) and other emissive nanomaterials. Solubility change PeNCs is achieved mainly by photoinduced thiol-ene click reaction between specially tailored surface ligands dual-role reagent, pentaerythritol tetrakis(3-mercaptopropionate) (PTMP), where enabled at low light intensity dose (~ 30 millijoules per square centimeter) strong activity PeNCs. The...
Europium halide perovskites are promising candidates for environmentally benign blue-light emitters with their narrow emission line width. However, the development of high-photoluminescence quantum yield (PLQY) colloidal europium perovskite nanocrystals (PNCs) is hindered by limited synthetic methods and elusive reaction mechanisms. Here, we provide an effective route achieving high-PLQY deep-blue-emitting CsEuBr
