Abstract

The Nd

-sensitized Ca

-doped NaYF

:Yb/Tm/Ca@NaGdF

:Nd/Yb core/shell upconversion nanoparticles were successfully prepared by solvothermal method. The effects of key factors such as the content of sensitizers Nd

and Yb

and the excitation power on the fluorescence performance were studied for the blue light and UV up-conversion emission generated in the Tm

multi-photon process. To obtain up-converting nanoparticles with good hydrophilicity

the UCNPs surface was modified with mesoporous silica(mSiO

). Its morphology

structure and fluorescence properties were characterized by TEM

XRD

FT-IR and fluorescence spectroscopy. The results showed that the prepared nanoparticles were pure hexagonal phase

the surface was evenly modified with a layer of mSiO

. Then

under

the excitation of 808 nm near infrared light

when the mole fraction of Nd

and Yb

in the shell was 50% and 10% respectively

it shows strong up-conversion blue light(

) and ultraviolet light(

). The research will have potential application prospects in photodynamic therapy and fluorescence imaging.
