在强磁场作用下，利用等离子体辐照法在离子液体表面合成了结构可控的金纳米粒子。在等离子体的边缘被照射的区域中容易合成AuNPs，而在核心等离子体被照射的区域中几乎不合成AuNPs。在等离子体边缘区域中，高能电子与中性气体碰撞，并且扩散的低能电子通过还原氯化金的Au离子而产生AuNP。另一方面，在核心等离子体区，高能电子的辐照使离子液体解离，生成具有氧化作用的新化合物，抑制了金纳米粒子的合成。
Structure controlled gold nanoparticles (AuNPs) are synthesized at the surface of the ionic liquid by the plasma irradiation under the strong magnetic field. The AuNPs are easily synthesized in the region where the edge of the plasma is irradiated, while hardly synthesized in the region where the core plasma is irradiated. In the plasma edge region, high energy electrons collide with neutral gas and the diffused low energy electrons generate the AuNPs by reducing Au ions of the gold chloride. On the other hand, in the core plasma region, the irradiated high energy electrons can dissociate the ionic liquid and generate the new compounds with oxidation effect, which inhibit the synthesis of the AuNPs.
