Abstract

We present a detailed, in situ study of photoluminescence of ultrathin perylene films on a Cu(110) surface. Temperature-dependent measurement has been correlated to the surface phase transition process. Different components of the fluorescence emission have been assigned to excimer, defect states, and monomer excitons. Most importantly, a coverage-dependent measurement has allowed us to identify that only emission from the first layer of the perylene is quenched by the metal substrate.
