Silica coated NaYF4:Yb,Er

Green Upconversion Luminescence(usually obtained at 980/525 and 544 nm excitation/emission wavelengths) is used for temperature measurement in turn. Then,the nanocomposites were applied to the dual-mode in vitro imaging of HepG-2 cells with temperature and O2.A novel multifunctional nano composite mesoporous silica coating NaYF4:Yb,Er@NaYF4 Upconversion ruthenium(II)complex nanoparticles have Green Upconversion Luminescence and red downconversion luminescence,which can be used for temperature detection,oxygen sensing and dual-mode cell imaging.
