Synthesis of Monodisperse CoPt3 Nanocrystals and Their Catalytic Behavior for Growth of Boron Nanowires

Monodisperse CoPh nanocrystals （NCs） have been synthesized in oleylamine solution by an organic solvothermal method. The NCs were ellipsoidal particles with a diameter around 6.6 nm and length around 10 nm with a good single crystal structure. Using CoPt3 NCs as catalysts, large-area boron nanowires with diameters ranging from 30 to 50 nm were successfully prepared by chemical vapor deposition using a C/B/B203 mixture as the precursor. Structural analysis indicated that these nanowires were single crystalline with a fl-rhombohedral structure. Measurement of the field emission properties of boron nanowire films showed that the boron nanowires have good field emission characteristics.

Monodisperse CoPt3 nanocrystals (NC ) 被一个器官的 solvothermal 方法在 oleylamine 答案综合了。NC 在有好单个水晶结构的 10 nm 附近是有在 6.6 nm 和长度附近的一条直径的椭圆体的粒子。把 CoPt3 NC 用作催化剂，有从 30 ～ 50 nm 的直径的大区域的硼 nanowires 被化学蒸汽免职成功地作为先锋用 C/B/B2O3 混合物准备。结构的分析显示这些 nanowires 是与菱形的结构水晶的单身者。硼 nanowire 电影的地排放性质的测量证明硼 nanowires 有好地排放特征。
