      abstract     = {We have developed inkjet-printed scattering layers for
                      enhanced light extraction in organic light emitting diodes
                      (OLEDs). These layers are based on scattering
                      polymer/nanoparticle composites, which are prepared from a
                      solvent-free process and used for the outcoupling of
                      waveguide modes to free propagating modes, thus improving
                      the device efficiencies. Two different monomers are examined
                      and an inkjet-printing process is developed for each of
                      them.Wefirst analyze the inks’rheological properties,
                      followed by the optical and morphological properties of the
                      resulting layers. Upon integration of these printed layers
                      into an OLED stack, the device efficiencies are increased by
                      up to $40\%$ with respect to an unpatterned reference
                      device. Furthermore, we show that these internal light
                      extraction layers improve the angular and spectral stability
                      of the devices.},
