Optical absorption, photosensitization, and ultrafast carrier dynamic investigations of CdSe quantum dots grafted onto nanostructured SnO2 electrode and fluorine-doped tin oxide (FTO) glass

CdSe quantum dots were grafted onto the planar fluorine-doped tin oxide (FTO) glass (a) and nanostructured SnO2 electrode (b). Optical absorption, photosensitization, and ultrafast carrier dynamics were studied and found to depend strongly on the morphology of the substrates.
