Mesoscopic Assembly of Magnetic Pd-Ni Nanocrystals into Ordered Arrays by Using Alkane Thiols
Abstract:Two-dimensional arrays of core–shell Pd561Nin (n = 38, 280, 561, 800, 1500, 3000, 4500) nanocrystals have been prepared by using alkanethiols. The arrays of Pd561Nin nanocrystals are particularly well ordered; those with high Ni coverage show a tendency to form multilayers or crystallites. Two-dimensional arrays also have been obtained of Pd561Ni3000 nanocrystals further covered by a Pd layer with a Pd561Ni3000Pd1500 composition.
