摘要： Organic diode detectors (10) with switchable photosensitivity are achieved using organic photo layers (12) in the photodiodes and a detector circuit (15, 16) which applies a reverse or forward bias voltage across the diodes. These diodes can be arranged in matrices which function as high-performance, two-dimensional image sensors. These image sensors can achieve full color or selected color detection capability.

摘要： This invention pertains generally to the field of light-emitting diodes, LEDs. More particularly, this invention relates to polymer LEDs which offer high brightness, high efficiency, and extended operating life, and which comprise: a transparent hole-injecting anode layer (11); an emissive layer comprising an electroluminescent polymer (12); and an electron-injecting cathode layer (13); the cathode layer comprises an ultra-thin layer of alkaline earth metal, such as calcium, strontium, and barium, having a thickness of about 100 Angstroms or less, typically from about 15 to about 100 Angstroms.

摘要： Long-lived organic light-emitting diodes are achieved by positioning a layer (15) comprising polyaniline in the emeraldine salt form directly contiguous with the anode side of the active light-emitting layer (14). Particular advantages are achieved if the emeraldine salt-containing layer (15) has a sheet resistance of at least about 1000 ohms per square which can be achieved by casting the layer (15) from solution in a polar solvent, most particularly, DMSO.
