通过水热法制备了高荧光效率的巯基丙酸修饰的水溶性CdTe量子点，对不同取样时间的CdTe量子点进行电化学发光强度测试，并对其电化学发光的测试条件（包括扫描速度、共反应剂浓度、缓冲液的pH 等）进行了优化，得到最佳测试条件；同时，在水合肼还原剂作用下用微波快速有效的合成了石墨烯，并在超声作用下制备了石墨烯-CdTe 量子点复合物，进一步提高了水溶性CdTe 量子点的电化学发光强度。

The hydrothermal method was applied to synthese water-soluble CdTe quantum dots with high fluorescence quan-tum yield, and the electrochemiluminescence of CdTe quantum dots was tested with different sampling time. Be-sides, the best conditions for testing electrochemiluminescence were obtained by optimizing the testing conditions including scanning rate, concentration of coreagent, pH of buffer solution, etc. Meanwhile, grapheme (RGO) was obtained rapidly and effectively by using hydrazine hydrate as reductant in the microwave reactor and graphene-CdTe quantum dots was prepared under ultrasound to further improve the electrochemiluminescence intensity of CdTe quantum dots.
