在高能辐射场（1.17 和 1.33MeV 伽马射线、9MeV 电子和 1.6GeV C 离子）下，从含有 Au3+ 和 Pd2+ 以及阳离子表面活性剂（十二烷基硫酸钠）的溶液中合成了双金属 Au-Pd 纳米颗粒。使用传统透射电子显微镜（TEM）和环形暗场扫描透射电子显微镜（ADF-STEM）观察通过照射合成的颗粒。通过伽马射线和C离子辐照合成的粒子呈现出具有Au核和Pd壳的核壳结构。讨论了纳米颗粒尺寸分布对剂量率的依赖性。 (C) 2009 Elsevier Ltd. 保留所有权利。
Bimetallic Au-Pd nanoparticles were synthesized under high-energy irradiation fields (1.17 and 1.33MeV gamma-rays, 9MeV electrons, and 1.6GeV C ions) from solutions containing Au3+ and Pd2+ and cationic surfactant (sodium dodecyl sulfate). Particles synthesized by the irradiation were observed using conventional transmission electron microscope (TEM) and annular dark-field scanning transmission electron microscopy (ADF-STEM). The particles synthesized by gamma-rays and C ion irradiation exhibit core-shell structure with a Au-core and a Pd-shell. The dependence of the size distribution of nanoparticles on the dose rate is discussed. (C) 2009 Elsevier Ltd. All rights reserved.
