Enabling Photon Upconversion and Precise Control of Donor-Acceptor Interaction through Interfacial Energy Transfer.

ABSTRACT: Upconverting materials have achieved great progress in recent years, however, it remains challenging for the mechanistic research on new upconversion strategy of lanthanides. Here, a novel and efficient strategy to realize photon upconversion from more lanthanides and fine control of lanthanide donor-acceptor interactions through using the interfacial energy transfer (IET) is reported. Unlike conventional energy-transfer upconversion and recently reported energy-migration upconversion, the IET approach is capable of enabling upconversions from Er³⁺, Tm³⁺, Ho³⁺, Tb³⁺, Eu³⁺, Dy³⁺ to Sm³⁺ in NaYF₄- and NaYbF₄-based core-shell nanostructures simultaneously. Applying the IET in a Nd-Yb coupled sen
