Enhancing Lanthanide-Doped Nanocrystal Upconversion Luminescence Could Improve Bioimaging, Displays
SINGAPORE, Oct. 11, 2021 — At the National University of Singapore (NUS), researchers amplified upconversion luminescence in protein-size lanthanide-doped nanocrystals. The group reconstructed the surface of the crystal to prevent surface-associated energy loss. Tests showed that the approach enhanced photon upconversion eleven thousand-fold. Highly luminescent lanthanide-doped nanocrystals are desirable for use in biomedical applications and optical imaging. However, a large portion of lanthanide dopants
