Abstract

The effect of film preparaton procedures on the photoluminescenee efficiency (PLE) of the luminescent polymer poly(m-phenylenevinylene-co-2,5-dioetyloxy-p-phenylenevinylene) (PmPV) were investigated. The PLE of PmPV films improved by 50% when the solution was degassed by bubbling argon gas prior to spin casting in an inert atmosphere and baking under vacuum. Photoinduced absorption measurements show that this preparation method reduces polaron photogeneration, causing an increase in the photoluminescence (PL) yield through a reduction in exciton quenching and excited state absorption.
