Electronic Energy Transfer between Donor and Acceptor Adlayers on Single-Crystal Surfaces: Distance and Coverage Dependence,

Abstract

Electronic energy transfer in surface adlayers is a mechanism of fundamental importance to surface photochemical processes. In this study, the electronic energy transfer from a donor p-terphenyl (TP) adlayer to an acceptor 9,10-diphenylanthracene (DPA) adlayer was studied using quantum yield measurements at 30 K and 85 K. These investigations employed an A1203(0001) crystal surface as a two-dimensional support on which donor, spacer and acceptor adlayers could be sequentially adsorbed. The quantum yield measurements were performed in ultra high vacuum (UHV) utilizing laser induced fluorescence techniques.
