摘要：

A strategy to realize dual-mode luminescence from identical Tb3+ is provided via Gd-sublattice-mediated energymigration and core-shell engineering techniques. By optimizing the structure of a NaGdF4:Yb/Tm@NaGdF4:Ce/Tb nanoarchitecture, both upconversion and downshifting emissions, originating from D-5(4) -> F-7(6,5,4,3) transitions of Tb3+, are achieved through Yb3+ -> Tm3+ -> [Gd3+](n) -> Tb3+ and Ce3+ -> [Gd3+](n) -> Tb3+ energy transfer processes, respectively.
