When an electron finds itself

You are looking at an AMOL display – a product of organic electronics (from the English abbreviation Active Matrix Organic , hydrogen and nitrogen can be obtain literally from natural sources, available in unlimit quantities. Environmental friendliness . Heavy metals are harmful to living organisms. But some of the synthetic blocks us to assemble the final organic emitter molecules can be isolat from natural raw materials. Resource intensity .  physical and chemical evaporation-spraying methods are us. And for organic compounds – solution methods. That is, after evaporation of the solvent from the solution with the emitter, the resulting layer is immiately ready for use.

To deposit silicon on the diode substrate

It is technologically simpler, faster and cheaper. Physical flexibility The silicon wafer breaks easily when you try to bend it. But a sensor made of organic molecules in Armenia Mobile Number List the form of a thin film easily takes the form of a substrate (for example, a finger).  explain such an efficient extraction of light in organic semiconductors in response to an external action (current transmission) by the phenomenon of thermally activat delay fluorescence (TADF). If we imagine that electrons in atoms are a kind of currency, then there are “rich” (electron-donor) and “poor” (electron-acceptor) atoms. Scientists artificially construct a molecule.

How Ls light up Novosibirsk scientists

Which the rich and “poor” parts are separat and maximally isolat from each other. When a molecule has such a structure, under the influence of electricity USA CFO or light, the “flame of revolution” flares up – a struggle for electrons arises between “rich” and “poor” atoms. It leads to the appearance of an exciton – an excitation state in an “hole” of an acceptor. Accompanying this struggle are flashes of light (the result of the decay of singlet excitons) and heat (the result of the decay of triplet excitons). To achieve the maximum glow effect, it is necessary to turn triplet excitons, which make up 75% of all emerging excitons, into singlet ones.
