Abstract

We introduce a novel instrument combining femtosecond pump-probe spectroscopy with broadband detection and confocal microscopy. The system has 200-fs temporal resolution and 300-nm spatial resolution. We present spatio-temporal maps of excited-state dynamics in polyfluorene-polymethylethacrylate blends.
