Abstract

A core-shell-shell nanostructure composed of NaGdF₄:Yb/Tm@NaGdF₄:Nd@NaYF₄ is developed to realize Yb³⁺-sensitized upconversion and downshifting luminescence in Nd³⁺ ions. The unusual photon conversion property stems from a gadolinium sublattice mediated Yb³⁺ → Tm³⁺ → Gd³⁺ → Nd³⁺ energy transfer pathway. The energy transfer processes are investigated by varying the dopant concentration and distribution, in conjunction with time decay measurements.
