      Investigation of triplet harvesting and outcoupling efficiency in highly efficient two-color hybrid white organic light-emitting diodes (Phys. Status Solidi A 8/2013)

      Organic light-emitting diodes (OLEDs) are promising candidates to replace current light sources such as incandescent bulbs and fl uorescent tubes. In this issue, Hofmann et al. (pp. 1467–1475) report on highly efficient white OLEDs that harvest otherwise unused triplet excitons from a blue fl uorescent emitter by adding a yellow phosphorescent compound. The CIE coordinates of the OLEDs can be adjusted over a wide range by varying the distance between exciton generation and triplet harvesting zone. The team utilized spectrally and time-resolved electroluminescence measurements and optical modeling to guide the design of these white triplet harvesting OLEDs. For a device with CIE color coordinates of (0.42/0.40), close to the warm white color point A, the group obtained nearly perfect Lambertian emission characteristics. This OLED achieves an external quantum efficiency of 9.4% and a luminous efficacy of 27.1 lm/W (at 1000 cd/m2) which can be further increased to 46 lm/W using outcoupling enhancement techniques. The photograph on the cover shows operating yellow and white OLEDs as well as the layer structure used to achieve triplet harvesting.

      Self-organization of nanospheres in trenches on silicon surfaces (Phys. Status Solidi A 8/2013)

      Katharina Brassat, Fabian Assion, Ulrich Hilleringmann and Jörg K. N. Lindner

      Article first published online: 14 AUG 2013 | DOI: 10.1002/pssa.201370048

      Thumbnail image of graphical abstract

      Self-organization of small objects is an effective approach of creating ordered nanostructures on a surface. On planar surfaces, nanosphere lithography (NSL) has recently attracted much attention, as it allows to rapidly create large-area nanopatterns on any wettable material at low cost. In NSL, spheres from a colloidal suspension are typically self-arranged in a hexagonally close-packed mono- or double-layer on a surface and the open spaces in between each triple of neighboring spheres serve as mask openings, where the subjacent substrate can be modifi ed by materials deposition or removal. Thus, NSL enables the fabrication of nanopatterned surfaces with good control of the size of surface features, their shape, density and order. On page 1485–1489, Brassat et al. show that using a spreading knife technique, spheres can also be arranged within linear trenches on silicon, where a self-organized molecular monolayer helps to suppress sphere deposition outside the trenches. The SEM image shows a double row of spheres in a trench in a cross-section view. The resulting nanostructures are assumed to pave the way to combine microfl uidics and nanoplasmonics in future devices.

      Thumbnail image of graphical abstract

      Singlet and triplet transfer processes are studied in white triplet harvesting organic light-emitting diodes, comprising fluorescent and phosphorescent emitter molecules. The CIE coordinates of these devices can be adjusted over a wide range by varying the distance between exciton generation and triplet harvesting zone. Optical modeling of the electromagnetic field and a comparison to the position of the emitters confirms that the devices operate close to the optical optimum.
