ACS Applied Nano Materials, 2(3), 1421-1430. doi:10.1021/acsanm.8b02315 | Journal: | ACS Applied Nano Materials | Abstract: | In this paper, an oxide upconversion nanomaterial, Gd2O3:Ln3+, as an alternative counterpart of NaGdF4:Ln3+ was developed via controlled surfactant-free synthesis, flexible lanthanide loading, compositional/size tuning, hexagonal-to-cubic lattice refinement, and positive surface charging to achieve a substantial enhancement of upconversion luminescence (∼30 times upon calcination at 1000 vs 600 °C; ∼4000 times versus its hydroxide form) due to high crystallinity and extremely low residual impurities for white emission and cellular imaging. | URI: | https://hdl.handle.net/10356/144499 | ISSN: | 2574-0970 | DOI: | 10.1021/acsanm.8b02315 | Schools: | School of Materials Science and Engineering | Rights: | This document is the Accepted Manuscript version of a Published Work that appeared in final form in ACS Applied Nano Materials, copyright © American Chemical Society after peer review and technical editing by the publisher.
