Abstract

The hierarchical self-assembly of Yb 3+ and Tm 3+ co-doped YF 3 elongated nanocrystals (NCs) into nanobundles of straw were synthesized through a facile hydrothermal route. The formational mechanisms of regular aggregates of the building blocks were studied. Ultraviolet (UV)-blue upconversion emissions of Tm 3+ were recorded under 980-nm excitation by the Yb 3+ sensitizer. The relatively bright blue emission indicated that the bundles have the potential for applications such as short-wavelength solid-state lasers and display devices.
