摘要

Lanthanide-doped upconversion nanoparticles,which enable the conversion of incident low-energy near-infrared (NIR) photons into higher-energy emissions (including NIR,visible,and UV light),have attracted considerable interests because of their promising applications in many fields,such as solar cells,biological imaging,three-dimensional displays,sensors,anti-counterfeiting and therapeutics [1,2].
