Abstract
Influence of KI salt on the spectral-luminescent properties of polymer films of P3HT has been investigated in this work. Addition of KI doesn't lead to significant changes in optical density of the polymer films, but significantly changes the intensity and lifetime of the luminescence of P3HT. Adding KI reduces the lifetime of P3HT luminescence. Growth of the luminescence intensity occurs at a low concentration of KI and its quenching occurs at the high concentrations. A significant increase in the electrical resistance of the films takes place by adding of the KI. Type of magnetic effects on the photoluminescence of P3HT depends on the concentration of KI. Changes in the magnetic effect in P3HT-KI films are connected with increase in the concentration of triplet states in the polymer.
