Abstract: Disclosed is an OLED configuration that although comprises an exciplex that has an emission spectrum that is redder than the emission spectrum of the emitter, the emission from the exciplex is suppressed so that the overall OLED emission spectrum is still dominated by the emission of the emitter.

Abstract: An organic light emitting diode (OLED) architecture in which efficient operation is achieved without requiring a blocking layer by locating the recombination zone close to the hole transport side of the emissive layer. Aryl-based hosts and Ir-based dopants with suitable concentrations result in an efficient phosphorescent OLED structure. Previously, blocking layer utilization in phosphorescent OLED architectures was considered essential to avoid exciton and hole leakage from the emissive layer, and thus keep the recombination zone inside the emissive layer to provide high device efficiency and a pure emission spectrum.

Abstract: A reconfigurable thin-film photonic filter weight bank comprises at least one photodetector and at least one optical filtering device comprising a pair of reflective thin film stacks with an interstitial medium cavity therebetween forming an optical cavity. Operation of a bank occurs when the reflective film is more selectively reflective to a range of frequencies and is more translucent to frequencies outside the range. The bank can reconfigurably weight signals by varying the cavity sizes or complex indices of refraction, with one photodetector integrating the weighted signals. Detectors can also be embedded inside the individual cavities to output unweighted, but demultiplexed, electrical signals. A neuromorphic opto-electronic system comprises a plurality of interconnected artificial optical neurons, each including at least one thin film neuromorphic opto-electronic device with a reconfigurable thin-film photonic filter weight bank. Related methods are also disclosed.

Abstract: Devices and techniques are provided for achieving OLED devices that include one or more enhancement layers formed at least partially from a plasmonic material exhibiting surface plasmon resonance that non-radiatively couples to an organic emissive material in the organic emissive layer, where a majority of excited state energy is transferred from the organic emissive material to a non-radiative mode of surface plasmon polaritons of the enhancement layer.
