Highlights The hydroiodic acid was explored systematically to modify PbS quantum dots (QDs) ink process, which could remove trap states by hydroxyl ligand and improve iodine passivation on the PbS-QDs surface. This strategy solved the essential question of PbS-QDs ink process and showed the favorabl...
