NaYF4:Yb3+, Er3+@SiO2@Au heterogeneous nanostructures, with the ability of integrating upconversion luminescence (UCL) and photothermal therapy as well as real-time temperature monitoring, have been successfully prepared. The UCL intensities of NaYF4: Yb3+, Er3+ nanocrystals showed an obvious reduction after gold nanoparticle attachment and gold shell coating, but it was found that they were independent of the SiO2 spacer layer thicknesses. The presence of gold nanostructures can significantly improve the photothermal conversion properties of NaYF4: Yb3+, Er3+ nanocrystals with an increased temperature up to 39 degrees C, while retaining their temperature sensing properties, manifesting their great potential as diagnostic and therapeutic tools for use in biomedical fields.
