Abstract

A facile preparation of highly fluorescent Ag nanoclusters (AgNCs) was synthesized using a surfactant-free N

N-dimethylformamide (DMF) reduction method by reflux at 140 ℃. The as-prepared samples were characterized by UV-Vis absorbtion spectroscopy

fluorescence spectroscopy and HRTEM. The results show that the AgNCs with small size emit strong blue fluorescence possessing excellent water-solubility and photostability. Moreover

the fluorescence from AgNCs can be efficiently quenched by Hg

. By virtue of the specific response

a new

simple

selective and sensitive fluorescent method for detecting Hg

has been developed based on DMF-AgNCs. This method shows a good linear relationship within the concentration range of 5.010

-9

~1.510

-7

mol/L

the detection limit was 3.010

-9

mol/L

and the correlation coefficient

= 0.995 8.
