Abstract

Using ultrafast time-delayed pump-probe measurements, the mechanisms leading to stimulated emission (SE) and photoinduced absorption (PA) in thin films and solution of poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylenevinylene] are studied. The change in the excited-state spectra is monitored by means of femtosecond time-resolved nonlinear spectroscopy in order to identify the SE and PA spectral regions and their time evolution. Femtosecond gain-narrowing measurements and the influence of the PA on the photoluminescence spectra are also presented. Bimolecular interaction at high excitation densities and independence of the PA and SE dynamics on the pump wavelength are demonstrated.
