The preparation and size control of III-V semiconductor nanomaterials are discussed. The preparation methods are divided into physical and chemical methods. Physical methods include ion implantation, sputtering and laser ablation. Chemical methods include high temperature organic liquid phase synthesis, organic solvent heating, hydrothermal and sol-gel processes. The high temperature organic liquid phase synthesis method is easy to prepare uniform size and stable semiconductor nanocrystals. The organic solvent heating method, the hydrothermal method and the sol-gel method are simple and the reaction conditions are mild, and have broad application prospects.
