In article number 2000289, Takayuki Chiba, Junji Kido and co‐workers demonstrate the development of mixed‐halide CsPb(Cl/Br) 3 nanocrystals (NCs) by ligand exchange with adamantane‐1,3‐diamine (ADDA) having a bidentate structure for the use in blue light‐emitting devices (LEDs). The ligand exchange of CsPb(Cl/Br) 3 NCs with ADDA improves photoluminescence quantum yield. Blue LEDs based on CsPb(Cl/Br) 3 NCs with ADDA reached a maximum external quantum efficiency of 1.1% at electroluminescence wavelength of 456 nm.
