Abstract :
We report on the optical properties of tris-(stilbene)amine (TSA) and its application as a light-emitting layer in a microcavity. Time-resolved photoluminescence spectroscopy on a blend of TSA in polycarbonate (PC) demonstrates that the dynamics of the optical excitations significantly depend on the detection energy and temperature. This behaviour is characteristic for hopping relaxation within an inhomogeneously broadened density of states. We have realized a microcavity based on TSA where the emission shows spectral narrowing, intensity enhancement and a change of the radiative lifetime at the wavelength resonant to the cavity mode.
