dc.description.abstractFluorescent carbon dots (CDs) with excitation-wavelength-dependent and excitation-wavelength-independent emission have been prepared with varying amounts citric acid (CA), ethylenediamin end-capped polyethylenimine (PEI-EC) and sodium borohydride (NaBH 4 ), their structure, optical and chemical sensing properties have been also systematically investigated. The varying of NaBH 4 and PEI-EC renders the structure and surface state change as well as photoluminescence (PL) properties. The results indicated that NaBH 4 made the CDs sensitive to Co 2+ ions, whilst the PEI-EC served to increase their sensitivity. The synergistic roles that both NaBH 4 and PEI-EC played on the selective and sensitive detection of Co 2+ were achieved via a simple adjustment of the mass ratios during synthesis. Furthermore, the PL intensity was gradually recovered until completely restored with the addition of chelating agent ethylenediaminetetraacetic acid (EDTA) to the Co 2+ quenched CDs solutions. This work provided quantitatively preparation and controllable synthesis of excitation-wavelength-dependent or independent CDs for the development of PL based sensors.en_US
