Perovskite nanocrystals (NCs) have attracted considerable attention for optoelectronic device applications due to their excellent optical absorption and emission properties. In this study, a dual-ligand strategy employing didodecyldimethylammonium bromide (DDAB) and 1,12-diaminododecane (DAD) was used to cross-link the nanocrystals, significantly enhancing their solvent resistance. Furthermore, the removal of excess ligands through octane washing, a good solvent, led to the development of a flexible X-ray detector exhibiting high sensitivity and low dark current.
