Spectroscopic and femtosecond dynamic measurements reveal that the rate of photoinduced electron/hole spatial separation decreases with increases in the size of the core, and it is independent of the thickness of the shell in the CdSe/ZnTe QDs. The results are consistent with the binding strength of the electron and hole confined at the center of CdSe. The correlation between the core/shell size and the electron/hole spatial separation rate resolved in this study may provide valuable information for applications where rapid photoinduced carrier separation followed by charge transfer into a matrix or electrode is crucial, such as in photovoltaic devices.application/pdf211046 bytesapplication/pdfen-US[SDGs]SDG7Binding energy; Charge transfer; Electrodes; Electrons; Matrix algebra; Photovoltaic cells; Semiconductor quantum dots; Separation; Synthesis (chemical); Thickness control; Electron/hole spatial separation; Femtosecond dynamics; Photoinduced carrier separation; Precursors; Semiconducting cadmium compoundsjournal article10.1021/jp049177w2-s2.0-4043102062WOS:000222864200014http://ntur.lib.ntu.edu.tw/bitstream/246246/164771/1/29.pdf
