摘　　要：以谷胱甘肽(GSH)为保护剂,通过考察不同反应温度、n(GSH)∶n(硝酸铜)、反应时间合成了荧光性能良好的GSH-Cu NCs。该GSH-Cu NCs合成简单,pH=4~8.5,GSH-Cu NCs荧光强度与pH呈良好的非线性关系,对pH响应良好,且具有较好的可逆性和选择性,为构建实时、便捷的pH传感分析提供了平台。Using Glutathione(GSH)as a protective agent,GSH-Cu NCs with good fluorescence properties was synthesized by investigating the reaction temperature,the mass ratio of GSH to copper nitrate,and the reaction time.The GSH-Cu NCs has the advantages of simple synthesis,in the range of pH 4.0~8.5,the fluorescence intensity of GSH-Cu NCs has a good nonlinear relationship with pH.It has good pH response,good reversibility and selectivity.It provides a real-time and convenient platform for pH analysis.
