In a planar thin film structure, light emission from OLEDs was strongly influenced by the interference effect. With suitable design of microcavity structure and layer thicknesses adjustment, optical characteristics can be engineered to achieve high optical intensity, suitable emission wavelength, and broad viewing angles. To increase the extractio© 2010 by the authors n efficiency from OLEDs and organic thin-films, corrugated structure with micro- and nanoscale were applied. Microstructures can effectively redirects the waveguiding light in the substrate outside the device. For nanostructures, it is also possible to couple out the organic and plasmonic modes, not only the substrate mode. © 2010 by the authors.Extraction efficiency; Microstructure; OLEDelectrode; ellipsometry; equipment design; film; light emitting diode; light refraction; light scattering; optical instrumentation; organic light emitting diode; oscillator; review; surface plasmon resonance; chemistry; diode laser; extraction efficiency; illumination; microstructure; OLED; glass; indium tin oxide; organic compound; tin derivative; extraction efficiency; microstructure; OLED; Electrodes; Glass; Lasers, Semiconductor; Lighting; Organic Chemicals; Tin Compoundsreview10.3390/ijms11041527204800332-s2.0-77951966879
