New paper: Quantification of Material Gradients in Core/Shell Nanocrystals
In this paper we quantify how steeply the material changes at the interface of graded core/shell nanocrystals. By using extended x-ray absorption fine structure spectroscopy we determine the coordination environment of one of the constituent ions. We show that cation diffusion is already strong at comparably low synthesis temperatures. At higher temperatures an ordered superlattice forms, which has not been reported before for these systems.
