Abstract：

Hot　electron　induced　cathodic　electrochemiluminescence　(ECL)　was　observed　at　screen　printed　carbon　electrodes　(SPCEs)　during　pulse　polarization.　The　thin　insulating　film　resulted　from　the　printing　inks　was　found　to　be　suitable　for　generating　hot　electrons,　which　can　further　be　converted　to　hydrated　electrons　and　induce　the　subsequent　luminescence.　Compared　with　disposable　Al/Al2O3　electrode,　SPCEs　show　more　stable　and　reproducible　ECL　in　a　wider　pH　range　without　background　emission.　A　sensitive　ECL　method　for　determination　of　quercetin　is　proposed.　The　detection　limit　is　8.0×10-10　mol　L-1(S/N=3),　which　is　two　magnitudes　lower　than　that　of　common　ECL　method.　©　2010　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
