Abstract

Herein, a Yb,Tm:NaYF₄@NaLuF₄/Mn:CsPbCl₃ quasi-core/shell heterostructure is synthesized with the assistance of silica. The strong upconverting and downshifting emission of Mn²⁺ ions was observed in the nanocomposite with a quasi-core/shell structure. The FRET process further improves the energy utilization efficiency of PQDs for UCNPs, which depends on the quasi-core/shell heterostructure. Considering the dual-model fluorescence emission behavior of Mn²⁺ ions, the stable Yb,Tm:NaYF₄@NaLuF₄/Mn:CsPbCl₃ nanocomposite is used in anti-counterfeiting applications.
