摘　　要：碳点(carbon dots, CDs)由于具有原料来源广泛、发光波长可调、光稳定性好、生物相容性好等优点,而吸引了研究者的广泛关注。本文研究了反应溶剂和掺杂剂对合成碳点(CDs)光学性能的影响。以对苯二胺为反应前驱体,采用一步水热/溶剂热法合成了CDs,通过调控反应溶剂和掺杂剂,CDs最佳发光峰位从440 nm移动到620 nm,实现了从蓝到红的多色发光。Carbon dots(CDs)have attracted wide attention of researchers owing to their advantages,such as,wide sources of raw materials,ad-justable luminescence wavelength,good light stability and good biocompatibility.The effects of reaction solvents and dopants on the optical properties of CDs were studied.CDs were synthesized by one-step hydrothermal/solvothermal method using p-phenylenediamine as precur-sor.By regulating the reaction solvents and dopants,the multicolor luminescence of CDs was adjusted from blue to red,and the optimal lumi-nescence peak of CDs shifts from 440 nm to 620 nm.
