Upconversion luminescence of Gd2O3:Ln3+ nanorods for white emission and cellular imaging via surface charging and crystallinity control

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...
