Rare‐Earth Oxide Nanopolyhedra, Nanoplates, and Nanodisks

Thermolysis of benzoylacetonate complexes proved successful in the synthesis of rare-earth oxide nanocrystals. CeO2 nanopolyhedra, Eu2O3 nanodisks, and Pr2O3 nanoplates display 2D ordering on copper grids (see figure), and the former two show interesting optical properties arising from surface-modification effects.
