| Abstract: | We synthesize small and uniform NiO nanocrystals, which can be potential for hole‐transporting of organic solar cells and transparent conducting material, based on a protecting ligand of lithium stearate by a hot‐injection method. And the reaction mechanism is alcoholysis of metal carboxylate salts with the protection ligand of lithium stearate binding to the surfaces of NiO nanocrystals to prevent them reduction into Ni. We find that the hot‐injection method is an effective way to prepare narrow size distribution and small size of NiO nanocrystals. The relatively superior optical transparency and flat surface features of the NiO nanocrystal thin films are also obtained. |
