Abstract: A light-emitting device is optimized for radiative recombination and minimizes non-radiative recombination. The light-emitting device includes an emissive layer, a first electrode and a second electrode from which charges are generated, a first charge transport layer that injects charges from the first electrode into the emissive layer, and a second charge transport layer that injects charges from the second electrode into the emissive layer. At least one of the charge transport layers includes a mixture of a first nanoparticle population and a second nanoparticle population, and the first nanoparticle population and the second nanoparticle population are conductive nanoparticles that are energetically non-aligned as between the first nanoparticle population and the second nanoparticle population. Nanoparticles of the first nanoparticle population and the second nanoparticle population are energetically non-aligned with each other by being made of different materials, by having nanoparticles of different sizes, and/or by having nanoparticles of different shapes.

Abstract: A measurement device for measuring a concentration of a component of a gas mixture includes a chamber that contains the gas mixture, a light source that emits light into the chamber, the emitted light having a wavelength between 230 nm and 320 nm, and a light sensor that detects a portion of the light from the light source that has propagated through the gas mixture. A processor is configured to determine the concentration of the component of the gas mixture based on the portion of the light emitted from the light source that is detected by the light sensor. The light source may include one or more LEDs, each having a central wavelength of light emission between 270 nm and 320 nm and a linewidth of less than 50 nm. The device may be employed to determine acetone concentration in exhaled breath, which may be indicative of diabetes or other health conditions.

Abstract: A nonlinear frequency conversion (NLFC) component is incorporated into a light source. The light source includes a light emitting element that emits a non-diffraction limited input light beam, and the NLFC component that exhibits walkoff and performs an NLFC process, such as second harmonic generation. An optical component is configured to converge the non-diffraction limited input beam into the NLFC component with a determined convergence half-angle. The convergence half-angle in air in a non-walkoff plane of the NLFC component is larger than a convergence half-angle angle for diffraction-limited light. Said convergence half-angle may be a multiple, ε×M, multiplied by the convergence half-angle value for diffraction-limited light, wherein ε has a value between a lower value equal to the larger of 0.4 and 1 M and an upper value of 5.0, where M is the square root of the beam quality factor for the non-diffraction limited light.

Abstract: A light-emitting device incorporates an electrode that includes conductive nanoparticles to increase emission performance. A light-emitting device includes a substrate; a first electrode disposed on the substrate between a viewing side of the light-emitting device and the substrate; a second electrode disposed between the first electrode and the viewing side of the light-emitting device, wherein the second electrode includes a layer of nanoparticles that are electrically conductive; and an emissive layer comprising quantum nanoparticles in electrical contact with the first electrode and the second electrode, wherein the first emissive layer includes a material that emits light when electrically excited. Multiple light-emitting devices may constitute sub-pixels that are combined into a pixel, such as for a display device, wherein each sub-pixel emits light of a different color.

Abstract: A light-emitting device has improved impact resistance over conventional configurations. Such a light-emitting device includes a display panel layer, a housing layer, an impact absorbing layer adjacent the housing layer, a metal layer that is disposed between the impact absorbing layer and the display panel layer and that is deformable during an impact on the light-emitting device, and a compliant layer that is disposed between the metal layer and the display panel layer that enables a shape of the display panel layer to be maintained when the metal layer is deformed. Due to a compliance or low stiffness of the compliant layer, a permanent deformation of the metal layer due to an impact or device shape change is not discernibly transferred into the shape of the display panel layer, and the shape of the display panel layer is essentially maintained so that an impact or shape change does not adversely affect display performance.
