Description
Summary:Oxide inside: The structure of a plutonium(IV) oxide nanoparticle (see picture; Pu green, O red and blue, Cl yellow) has been determined by single‐crystal diffraction in the solid state and verified in aqueous solution by high‐energy X‐ray scattering. The nanoparticles are composed of 38 Pu ions arranged in an oxide lattice with a structure slightly distorted from the fluorite phase seen in PuO2. An absorption spectrum of the Pu clusters in solution is consistent with the classic Pu‐polymer optical response.
