Abstract: Disclosed is a non-invasive biometric sensor including a light source, an organic photodetector, and a detector. The light source is configured to irradiate light in a desired (and/or alternatively predetermined) wavelength range to a body part. The organic photodetector is configured to sense the light in the desired (and/or alternatively predetermined) wavelength range in response to the light in the desired (and/or alternatively predetermined) range being transmitted through the body part. The detector is configured to determine biomedical information of the body part based on an amount of the light sensed by the organic photodetector.

Abstract: A light emitting device includes: a first electrode and a second electrode with a surface facing the first electrode; an emission layer disposed between the first electrode and the second electrode and including a quantum dot (e.g., a plurality of quantum dots); and an electron auxiliary layer disposed between the emission layer and the second electrode. The electron auxiliary layer includes a first layer including a first metal oxide, and a second layer disposed on the first layer and including a second metal oxide. A roughness of an interface between the second layer and the second electrode is less than about 10 nm as determined by an electron microscopy analysis. An absolute value of a difference between a conduction band edge energy level of the second layer and a work function of the second electrode may be less than or equal to about 0.5 eV, and a conduction band edge energy level of the first layer may be less than the conduction band edge energy level of the second layer.
