The preferential positioning of different cations near the surface or at the center of small layered CdSe-ZnSe particles believed to have a shell-core structure has been demonstrated by the relative attenuation of the primary photoelectron and X-ray excited Auger signals from each cation. The preparation of the layered particles is described, and their absorption spectra are compared with those observed in "unstructured" particles of like composition.
