dc.description.abstract Based on chelation-enhanced fluorescence, a new fluorescent coumarin derivative probe 3(1-(7-hydroxy-4- methylcoumarin)ethylidene)hydrazinecarbodithioate for Hg2+, Ag+ and Ag nanoparticles is reported. Fluorescent probe acts as a rapid and highly selective “off–on” fluorescent probe and fluorescence enhancement by factors 5 to12 times was observed upon selective complexation with Hg2+, Ag+ and Ag nanoparticles. The molar ratio plots indicated the formation of 1:1 complexes between Hg2+ and Ag+ with the probe. The linear response range covers a concentration range 0.1 10–5–1.9 10–5mol/L, 0.1 10–5–2.3 10–5mol/L and 0.146 10–12–2.63 10–12mol/L for Hg2+, Ag+ and Ag nanoparticles, respectively. The interference effect of some anions and cations was also tested. Copyright © 2013 John Wiley & Sons, Ltd. en_US
