Abstract
Advancement in the development of electroluminescent devices utilizes conjugated polymers as lasing materials. A polymer with stimulated emission and large optical gain was investigated. The photoluminescence was measured using a streak camera after passing through a monochromator. Pump-probe experiments with femtosecond pulses was conducted to study the dynamics of the absorption changes and the optical gain. The spectral shape of the time-integrated photoluminescence as a function of excitation intensity is presented. Doubling the excitation intensity results in an increase of the integrated emission by more than two orders of magnitude.
