摘要：

Near-infrared upconverting NaYF4:Yb3+, Tm3+ nanophosphors modified with poly(acrylic acid) were prepared and characterized by transmission electron microscopy and luminescence spectroscopy. Based on the observed overlap between the emission spectrum of the NaYF4:Yb3+, Tm3+ nanophosphors and the absorption spectrum of the gold nanorods, we believe that a new "turn-off" luminescence resonance energy transfer aptamer sensor was constructed for sensing thrombin in near-infrared region.
