摘要

We have observed the poly(p-phenylene vinylene)(PPV) thin film based light emitting devices with a multifunction laser scanning microscope. The spatial distribution of PPV thin film's reflectivity, photoluminescence, and photocurrent are imaged. In addition, site dependent optical density and photocurrent spectra are also measured, which reveal the nature of optical excitations within PPV. The contrast between photoluminescence and photocurrent images is attributed to field induced luminescence quenching under exciton model.¹.
