Construction of Au@NaYF4:Yb3+,Er3+/Ho3+ bifunctional hybrid nanocomposites with upconversion luminescence and photothermal properties

The Au@NaYF₄:Yb³⁺,Er³⁺/Ho³⁺ bifunctional hybrid nanocomposites are constructed by a facile solution route, they simultaneously take advantage of both upconversion luminescence of NaYF₄:Yb³⁺,Er³⁺/Ho³⁺ nanocrystals and photothermal transduction property of AuNPs.
