Abstract

A new route was developed to synthesize CdSe quantum dots (QDs) in aqueous solution by hydride generation. High quantum yield and stabilized CdSe QDs were prepared by introducing H

Se gas which was generated on-line by reducing SeO

with KBH

into the aqueous medium containing Cd

ions. The prepared CdSe QDs were successfully utilized for analysis of Ag

in environmental water samples and cells. The limit of detection is 0.005 gmL

-1

and the relative standard deviation is better than 2.7%(

=7). The proposed method retains several unique advantages

including sensitivity

simplicity

stability and environmentally friendly.
