Characteristics of organic light-emitting diodes (OLEDs) with SiO2-based scattering layers. a Current density (J)−luminance (L)−voltage (V) characteristics. b−d External quantum efficiency (b), power efficiency (c), and current efficiency (d) vs. L. Layout of the devices used in this figure follows that of Type A defined in Fig. 4b. e Photographs of OLEDs with SiO2-embedded scattering layers according to scatterance (S). Photographs were taken at current density of 0.1 mA cm−2
