Single‐crystalline, cubic ZrO 2 ‐ and HfO 2 nanobelts have been fabricated via a direct thermal‐decomposition process under atmospheric pressure. The formation of cubic nanobelts can be controlled by varying the dopant concentration of nanobelt precursors, heating temperatures, and heating rates. The lanthanide‐doped nanobelts show a dual capability for both down‐ and up‐conversion emissions (see picture) in the visible range.
