Eiselt, Thomas; Preinfalk, Jan; Gomard, Guillaume; Graf, Dennis; Lemmer, Uli; Hanemann, Thomas

Abstract (englisch):

In this report, new scattering films for the application as light extraction layers in OLEDs are presented. They consists of an epoxy acrylate (Syntholux 291EA) and are manufactured with the help of a modified ink-jet printer Pixdro LP50.The exact ink composition and the adapted piezo power characteristic are presented in section 3. The ink has an optimized viscosity of 11 mPas and the particles are smaller than 1 um. The printed layers show a scattering intensity of 65 % at a wavelength of 500 nm and the total Transmission is about 80 % in the visible range.
