摘要：
Near-infrared luminescence of Yb3+ can be sensitized by forming complex with 1-(2-pyridylazo)-2-naphthol (PAN). A novel near-infrared fluorometric method for the determination of Yb3+ in rare earth mixture was suggested. The result shows that the linearity range is 1.0 x 10(-6) similar to 8.0 x 10(-6) mol/L with detection limit of 1.0 x 10(-6) mol/L, and the relatively standard deviation is 3.2%.
