摘要： Embodiments of the disclosed subject matter provide an organic light emitting diode (OLED) having an anode, a cathode, an emissive layer disposed between the anode and the cathode, and a hole blocking layer disposed between the emissive and the cathode. The emissive layer may include a phosphorescent dopant, where the phosphorescent dopant has an emission in 0.5% doped PMMA (Poly(methyl methacrylate)) thin film with a peak maximum wavelength that is greater than or equal to 600 nm at room temperature. The energy of a highest occupied molecular orbital (HOMO) of the phosphorescent dopant may be lower than or equal to −5.1 eV, and the energy of the HOMO of the hole blocking layer is at least 0.1 eV lower than the energy of the HOMO of the phosphorescent dopant.

摘要： Compounds that are organic radicals that can have a dual function. The compounds can be fluorescent emitters that emit in the near-IR. The compounds can also facilitate reverse intersystem crossing (RISC) to convert triplet excitons in an OLED to singlet excited states to maximize utilization of generated excitons in the OLED and approach 100% internal quantum efficiency.

摘要： Embodiments of the disclosed subject matter provide a wearable device that includes an organic light emitting diode (OLED) light source to output light having one peak wavelength from a single OLED emissive layer, and a first barrier layer that is disposed over or between the single OLED emissive layer and one or more down-conversion layers. One or more regions of the single OLED emissive layer are independently switchable and controllable so that the wearable device is configurable to output a plurality of wavelengths of light. One of the plurality of wavelengths of light that is output is near infrared light.
