β-cyclodextrin (β-CD) functionalized CdTe quantum dots (QDs) were prepared with β-CD and mercaptopropionic acid (MPA) as the stabilizers (denoted as β-CD-MPA-CdTe). The QDs capped with the dual stabilizers, β-CD and MPA, not only showed improved electrochemiluminescence (ECL) efficiency and higher ECL intensity due to the effective removal of the nonradiative surface state and deep surface trap of...
Water-soluble and stable CdTe quantum dots (QDs) capped with glutathione (GSH) and thioglycolic acid (TGA) were synthesized (denoted as GSH-TGA-CdTe) and the electrochemiluminescence (ECL) behavior of the QDs was investigated. As a result of specific interaction between the GSH and Pb 2+ , the ECL of the QDs was selectively reduced in the presence of Pb 2+ . Due to the low ECL intensity...
