Abstract: The invention relates to an organic light-emitting device (OLED) comprising at least: a first electrode; a second electrode; an organic light emissive layer arranged between said first electrode and said second electrode; and an organic charge transport layer arranged between said first electrode and said emissive layer, wherein i) the charge transport layer is patterned or provided with a periodic surface structure on a surface of the charge transport layer facing the emissive layer, and/or ii) an alignment layer which allows for charge transport to the emissive layer is provided between said charge transport layer and said emissive layer, which alignment layer promotes alignment of the optical dipoles of molecules of said light emissive layer towards a common preferred direction of the molecular axes. The use of the patterned or structured charge transport layer and/or the alignment layer provides improved light out coupling from the OLED layer stack, i.e. increased external quantum efficiency.

Abstract: The present invention relates to an encapsulation for an electronic thin film device, comprising a first barrier layer (108), a second barrier layer (112), and a first planarization layer (110?) for reducing the formation of pinholes in a subsequent barrier layer, said first planarization layer (110?) arranged between the first barrier layer (108) and the second barrier layer (112), wherein the first planarization layer (110?) is composed of a first plurality of planarization segment (114) having areas formed between each other, and the encapsulation further comprises a second planarization layer (116) arranged between the second barrier layer (112) and a third barrier layer (120), wherein the second planarization layer (116) is composed of a second plurality of planarization segments (118) arranged to extend over the areas between the first plurality of planarization segments (114), thereby further reducing the number of pinholes providing passageways through the encapsulation.

Abstract: An apparatus (1) for treatment with radiation for personal care, comprising a housing (2) provided with a UV source (3) and a wall (4) made of UV-transparent material which covers the housing (2) and which has a central area (7) and side areas (8) adjoining the central area (7). The wall (4) has a lower transmission to radiation with a wavelength <320 nm near the central area (7) than near the side areas (8). Thus the effective radiation energy of radiation with a wavelength <320 nm reaching the side portions of the irradiation plane (9) approximates a value of 0.14 W/m2 (European standard EN 60335-2-27), while the effective radiation energy of radiation with a wavelength <320 nm reaching the central portion of the irradiation plane (9) also approximates this value. This results in a practically uniform distribution of effective radiation energy of radiation with a wavelength <320 nm over the radiation surface (9) as a whole.

Abstract: The invention relates to an optical element comprising a substrate which is provided with a transparent layer comprising an organic polymer network and one or more photochromic compounds, in which the transmission of the optical element in the visible wavelength range changes in response to a variation of incident light, while the transparent layer comprising photochromic compounds is provided with a protective coating on the side remote from the substrate side.

Abstract: A substrate (22) is provided with a layer (21) comprising organo-metallic components (23) in a solvent having a high-boiling point component (24). As the solvent is removed, the high-boiling point component phase separates, forming larger globules (26) in a matrix (25). The-high-boiling point component is thereafter removed, leaving a matrix (12) of a substance such as SiO2, in which cavities (13) filled with gas or air of vacuum are present. The cavities have sizes from 5 to 200 nm.
