通过水热法，以Zn离子作为掺杂材料，L-半胱氨酸为稳定剂，制备出了水溶性的掺杂型CdZnTe量子点。应用高温高压的水热合成法，有效地减少了量子点表面的缺陷，过渡金属Zn的掺杂有效降低了CdTe 量子点的毒性，结果表明：制备出的CdZnTe量子点含有高比例掺杂剂，性质稳定、单分散性好、量子产率高，具有良好的生物相容性，可广泛应用于生化检测和生物医学研究。

In this paper , a novel water-soluble Zn2+doped CdTe quantum dot was prepared with L-cysteine as stabilizer through hydrothermal route .Due to the high temperature and high pressure in the process , the defects on the quantum dot surface were effectively reduced , together with its toxicity due to the addition of transition metal Zn ions .The as-prepared CdZnTe alloyed QDs demonstrated high quantum yield , high stability and excellent bio-compatibility and might be widely used in biochemical detection and biomedical research .
