We report a facile methodology to restore photoluminescence (PL) of CsPbBr3 nanocrystals (NCs) based on their postsynthetic modification with 3-aminopropyltriethoxysilane (APTES). By this methodology, a stark PL recovery factor of near 2-fold was obtained compared to their uncoated counterparts. 1H...
