Figure 3From: Facile synthesis of fluorescent Au/Ce nanoclusters for high-sensitive bioimaging Elemental analysis of Au/Ce NCs. (A) EDS of the Au/Ce NCs formed by hydrothermal synthesis. (B) and (C) were X-ray photoelectron spectra (XPS) evidencing the Au 4f and Ce 3d photoelectron emission from the Au/Ce NCs, respectively.Back to article page
