A direct view onto the carrier dynamics in graphite at the H point

Abstract

The photophysics of charge transfer between the electron donating, surface adsorbed D149 dye and an electron accepting porous ZnO film was investigated by measuring excited state lifetimes using ultrafast transient absorption spectroscopy. We systematically varioed the production scheme of the sample including the electrolyte. © Owned by the authors, published by EDP Sciences, 2013.
