Abstract X-ray absorption fine structure spectroscopy and scanning electron microscopy were used to study the atomic short range order structure, surface morphology and thickness of cobalt films electrodeposited from CoCl2 solutions on gold-coated Kapton. While the morphology on the electrodeposits strongly depends on the deposition time and thereby on the film thickness, the short range order structure deduced from the X-ray spectroscopic experiments suggests that pure metal films were formed, however with a slight relaxation of the Co-Co bond distances with increasing thickness, which may open new routes for the preparation of nanostructured Co-materials.

钴电沉积的 EXAFS 研究

摘要 采用X 射线吸收精细结构光谱和扫描电子显微镜，研究了CoCl2 溶液在镀金Kapton 上电沉积的钴薄膜的原子短程有序结构、表面形貌和厚度。虽然电沉积物的形态很大程度上取决于沉积时间，从而取决于薄膜厚度，但从 X 射线光谱实验推导出的短程有序结构表明形成了纯金属薄膜，但是 Co-Co 的轻微弛豫键距离随着厚度的增加而增加，这可能为纳米结构的 Co-材料的制备开辟新的途径。
