Magnetic Tuning of Upconversion Luminescence in Lanthanide‐Doped Bifunctional Nanocrystals

Abstract

Nanocrystal clear: Optical-magnetic (OM) bifunctional NaGdF4:Nd3+,Yb3+,Er3+ nanocrystals were successfully synthesized that consist of luminescent Er3+ ions and a coordinating magnetic Gd3+ ion. The luminescence of NaGdF4:Nd3+,Yb3+,Er3+ nanocrystals was tuned by changing the applied magnetic field (see figure) both at room temperature and ultralow temperatures.
