Multilayered nanoheterostructures: theory and experiment

Multilayered spherical CdS/HgS nanocrystals consisting of two embedded HgS layers in CdS and multilayered ZnS/CdS nanocrystals with one embedded CdS layer in ZnS are prepared and are characterized by optical spectroscopy, XRD (X-ray diffractometry) and TEM (transmission electron microscopy). The results of the optical spectroscopy are compared to theoretical calculation and TEM results are compared to TEM simulations.
