In this work, an effective strategy through doping of univalent Na+ ions, which are stable against oxidation and reduction, was proposed to enhance the emission efficiency and stability of orthorhombic CsPbBr3 nanocrystals (NCs). Compared with the fresh CsPbBr3 NCs, a better color purity and a highe...
