制备了聚丙烯酸修饰的NaYF4：Yb3+，Tm3+近红外上转换发光材料，并用透射电镜和荧光光谱对其进行了表征。基于NaYF4：Yb 3+，Tm3+纳米荧光粉的发射光谱与金纳米棒的吸收光谱之间的重叠，我们认为构建了一种新的“关断”发光共振能量转移适体传感器，用于近红外区域的凝血酶传感。
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.
