| 英文摘要 | (pdda/cdte)(n) layer-by-layer (lbl) film immobilized with fe(cn)(6)(3-) was fabricated on the gold electrode. electrochemical impedance spectroscopy (eis) and cyclic voltammetry (cv) were used to investigate the electrochemical properties of this film. the peak current of the immobilized fe(cn)(6)(3-) increased as the number of the bilayers increased and was proportional to the scan rate. compared with pure (pdda/cdte)(n) and (pdda/pss)(n) lbl film, fe(cn)(6)(3-) immobilized (pdda/cdte)(n) lbl film had good electron transfer ability. the immobility of fe(cn)(6)(3-) into the film was attributed to its interaction with cd2+ on the surface of cdte qds. fe(cn)(6)(3-) also can interact with other metal ions, which would make fe(cn)(6)(3-) release from the film. the concentrations of metal ions will affect the cv response of fe(cn)(6)(3-) immobilized lbl film. it has provided a novel prototype of device or sensor for quantitative detection of metal ions. |
