摘要

Gold nanoclusters dispersed in single crystal MgO were prepared by ion implantation and subsequent annealing at 1000 deg C.The morphological feature,size,crystallographic orientation of the Au nanoclusters with respect to the MgO matrix,and the interface structure between the Au nanoclusters and MgO were investigated using transmission electron microscopy.During annealing,the Au clustres nucleate coherently in the MgO lattice,leading to an epitaxial orientation relationship of [010]_(MgO)//[010]_Au and (200)_(MgO)//(200)_Au that is maintained for all the Au clusters.A critial size for the coherent-semicoherent interface transition is observed to be in the range from approx 5 to 8 nm for Au clusters in MgO.Au clusters larger than this critical size exhibit faceting on the {001} planes.The precipitated Au also exhibits internal dislcoations.
