摘要：

The production of nanosized semiconductor nanostructures composed of a core of CdS nanocrystals coated with a ZnS layer has been attempted by using a method of inverted micelles. The structural aspects of nanocrystals have been investigated by high-resolution transmission electron microscopy. The CdS/ZnS core/shell heterostructure has been evidenced. The epitaxy of ZnS on CdS has been observed, abrupt CdS-ZnS interfaces have been found and the accommodation mode between the two materials has been analysed. It has been shown that the ZnS shell grows with the same structure as the CdS core, which is either in the cubic blende-type structure or in the hexagonal wurtzite-type structure.
