“…Furthermore, the emitter lifetimes need to be compatible with the RC-time of the OLED to avoid emitter saturation effects [[31]]. In contrast to fluorescence, where emission originates from the lowest excited singlet state, phosphorescent EL induces thermalization losses in the order of the singlet-triplet splitting [ [112]] for every exciton that is captured by it via energy transfer from host materials or ISC [ [113]]. The loss might be circumvented if the excitons are resonantly generated on the emitter dopant.…”

White organic light-emitting diodes (OLEDs) are ultra-thin, large-area light sources made from organic semiconductor materials. Over the last decades, much research has been spent on finding the suitable materials to realize highly efficient monochrome and white OLEDs. With their high efficiency, color-tunability, and color-quality, white OLEDs are emerging to become one of the next generation light sources. In this review, we discuss the physics of a variety of device concepts that are introduced to realize white OLEDs based on both polymer and small molecule organic materi als. Owing to the fact that about 80 % of the internally generated photons are trapped within the thin-film layer structure, we put a second focus on reviewing promising concepts for improved light outcoupling.Comment: 53 pages, 51 figures, to be published in Review of Modern Physic

“…A typical mechanism for creating color centers is nonradiative recombination of a self-trapped exciton, demonstrated in alkali halides, or involves a self-trapped electron or hole that occur in many solids [52,53]. The lattice structure in the region of trapping may be sufficiently weak to give in to the local distortions, resulting in a vacancy or/and interstitial creation.…”

“…Seborrheic dermatitis (SD) is a common inflammatory erythematous-squamous dermatosis characterized by well-defined, erythematous scaly patches that appears in areas of increased sebaceous gland activity [35]. Currently, SD is diagnosed primarily through naked eye examination by the clinicians and dermatoscope images have been shown to be helpful in revealing characteristic features associated with SD [36].…”

A preliminary clinical trial using state‐of‐the‐art multiphoton tomography (MPT) and optical coherence tomography (OCT) for three‐dimensional (3D) multimodal in vivo imaging of normal skin, nevi, scars and pathologic skin lesions has been conducted. MPT enabled visualization of sub‐cellular details with axial and transverse resolutions of <2 μm and <0.5 μm, respectively, from a volume of 0.35 × 0.35 × 0.2 mm3 at a frame rate of 0.14 Hz (512 × 512 pixels). State‐of‐the‐art OCT, operating at a center wavelength of 1300 nm, was capable of acquiring 3D images depicting the layered architecture of skin with axial and transverse resolutions ∼8 μm and ∼20 μm, respectively, from a volume of 7 × 3.5 × 1.5 mm3 at a frame rate of 46 Hz (1024 × 1024 pixels). This study demonstrates the clinical diagnostic potential of MPT/OCT for pre‐screening relatively large areas of skin using 3D OCT to identify suspicious regions at microscopic level and subsequently using high resolution MPT to obtain zoomed in, sub‐cellular level information of the respective regions (© 2013 WILEY‐VCH Verlag GmbH & Co.
