Abstract :
We have investigated the effect of addition of stearic acid in poly(N-vinylcarbazole) (PVCz) films doped with perylene. Samples were prepared by spin coating technique and characterized by photoluminescence (PL) and Fourier transform-infrared (FT-IR) absorption. It was elucidated that PL emission due to perylene at 450 nm and 480 nm was enhanced and the concentration quenching of the perylene emission was reduced by the addition of stearic acid. Orientation ordering of carbazole base plane and/or perylene ring plane was suggested from IR measurement.
