	通过一步水热法制备了铕掺杂的碳量子点(Eu-CDs)，在磷酸盐缓冲介质中，Eu-CDs对鲁米诺–高锰酸钾化学发光体系具有增敏作用，而Ag<sup>+</sup>对Eu-CDs-Luminol-KMnO<sub>4</sub>化学发光体系有明显增强作用，据此建立了化学发光法测定痕量Ag<sup>+</sup>的新方法，线性范围是0.5~30 ng？mL<sup>？1</sup>，方法检出限是0.08 ng？mL<sup>？1</sup>，相对标准偏差为2.1% (n = 11, c = 15 ng？mL<sup>？1</sup>)。该方法成功应用于食品包装材料中银离子的检测，回收率在91%~117%之间。<br />
Europiumdoped Carbondots (Eu-CDs) was prepared through one step hydrothermal method. In phosphate buffer medium, Eu-CDs has great sensibilization to the Luminol-KMnO4 chemilumines-cence. Furthermore, it was found that Ag<sup>+</sup> could enhance the Eu-CDs-Luminol-KMnO<sub>4</sub> chemilumi-nescence system. Based on this, a new method for the determination of trace Ag<sup>+</sup> by chemilumi-nescence was established. The linear range was 0.5 - 30 ng？mL<sup>？1</sup>. The detection limit was 0.08 ng？mL<sup>？1</sup>; the relative standard deviation was 2.1% (n = 11, c = 15 ng？mL<sup>？1</sup>). The authors successfully applied this method to the detection of silver ions in food antibacterial packaging boxes, and the recovery rate was between 91% and 117%.
