Colloidal Synthesis of Monodisperse High-Entropy Rare-Earth Oxide Nanoplatelets
High-entropy rare-earth oxides (HE-REOs) offer a broad compositional space for tuning defect chemistry, lattice distortion, and local atomic environments, yet their controlled synthesis as monodisperse and structurally well-defined nanostructures remains challenging. Here, we report a colloidal approach for the synth...
