摘　　要：以丙三醇为原料,经一步微波法制备了碳量子点(CDs),所制备的碳量子点粒径分布在4~25 nm之间,其平均粒径为16.5 nm.荧光光谱结果表明,相比于Cu^(2+),Ca^(2+),Mn^(2+),Co^(2+),Fe^(2+),Ni^(2+),Zn^(2+),Na^(2+)Cd^(2+),Mg^(2+),Pb^(2+),K^+和Ag^+等13种常见金属离子,该碳量子点对Fe^(3+)显示出高选择识别性,且Fe^(3+)浓度在10~60μmol/L之间呈现良好的线性关系,检出限为2μmol/L.Glycerol was selected as sole starting material by one step microwave method for prepared a new type of carbon quantum dots（CDs）.The size of th CDs distribute in 4-25 nm with the average particle size of16.5 nm.In addition,the resulting CDs could exhibit a highly sensitive fluorescence response behavior to Fe^3＋ compared to other 13 kinds of metal ions including Cu^2＋,Cu^2＋,Zn^2＋,Co^2＋,Fe^2＋,Ni^2＋,Mn^2＋,Na^＋,Cd^2＋,Mg^2＋,Pb^2＋,K^＋ and Ag^＋.The detection limit of Fe^3＋ was calculated to be 2 μmol/L with a linear dynamic range of 10-60 μmol/L.
