Abstract

Pump-power tunable white upconversion (UC) emission under the excitation of a 980 nm laser diode from lanthanide-doped hexagonal NaYF₄ nanorods synthesized by a hydrothermal method is reported. The calculated color coordinates reveal that the UC white color output from both the Yb ³⁺-Ho³⁺-Tm³⁺ and Yb³⁺-Er ³⁺-Tm³⁺ triply-doped systems can be fine-tuned for a wide range of pump-power densities, but each has its own superiority. The former has a broader response scope to pump-power densities for white emission and the simulated white color output can be tuned more precisely, whereas the latter has a much broader range of white color output under the same pump-power densities. These desirable properties make these Ln³⁺ doped hexagonal NaYF ₄ nanostructures promising in applications such as miniaturized solid-state light sources, multicolor three-dimensional display devices, optical processing sensors and multicolor labels for bioprobe and bioimaging. © 2011 Elsevier B.V.
