Electron and Hole Transfer from Indium Phosphide Quantum Dots
Get PDFElectron-and hole-transfer reactions are studied in colloidal InP quantum dots (QDs). Photoluminescence quenching and time-resolved transient absorption (TA) measurements are utilized to examine hole transfer from photoexcited InP QDs to the hole acceptor N,N,Nâ˛,Nâ˛-tetramethyl-p-phenylenediamine (TMPD) and electron transfer to nanocrystalline titanium dioxide (TiO 2 ) films. Core-confined holes are effectively quenched by TMPD, resulting in a new âź4-ps component in the TA decay. It is found that electron transfer to TiO 2 is primarily mediated through surface-localized states on the InP QDs
