The fluorescence of Cu nanoparticles was shown to decrease with an increase in concentration of manganese ion with a high correlation coefficient. Then we use the same method for the synthesis of the gold nanoparticles stabilize by histidine and 6-mercaptohexanoic acid. The resulting gold nanoparticles were applied for the detection of pH value in aqueous solution with a high correlation coefficient. UV/Visible spectroscopy, fluorescence spectrophotometer, high-resolution transmission electron microscopy, high-resolution X-ray photoelectron spectrometer, time-resolved photoelectron spectroscopy and dynamic thermal gravity analyzer were used to investigate the physical and chemical properties. The results demonstrated that we did make the copper and gold nanoparticles successfully. In addition, two kinds of nanoparticles can be applied for the detection of manganese ion concentration and pH value in aqueous solution, respectively. Therefore, this work can be applied for the of environmental samples as new analytical probes.改良式Brust-Schiffrin單相合成方法銅奈米團簇金奈米團簇二價錳離子pH值Modified Brust-Schiffrin methodcopper nanoparticlesgold nanoparticlesmanganese ionpH value
