According to the FIAN-Inform Scientific Information Agency, staff members of the RAS Institute of Physics named after P. Lebedev (FIAN) in cooperation with scientists from the Moscow Physico-Technical Institute and the Institute of Physics of the National Academy of Ukraine developed a technology to produce new planar (from Latin planus--flat, plane) metalloorganic structures that can be used to manufacture submicron electroluminescent light sources with a controlled emission spectrum.
Conversion to new lighting technologies is a crucial point for modern society. The EU and the USA are already in the process of getting rid of conventional incandescent light bulbs. For example, the EU countries are planning to replace them with energy-saving lamps till 2012. In the USA they will be totally withdrawn from sale till 2014. It is possible that Russia will also prohibit traditional lamps to increase overall energy efficiency. Quite popular luminescent lamps, irrespective of high demand, are difficult to be manufactured and utilized. That's why specialists are in active search for new types of sources based on semiconductor or organic light-emitting diodes, in which the so-called OLED technologies are used (from English Organic Light-Emitting Diode). The Russian and Ukrainian scientists suggest to focus on potentialities of electroluminescent characteristics of metalloorganic structures.
In 2010, there was produced a pilot batch of such low-molecular materials at FIAN. Dmitry Chubich, Cand. Sc. (Phys. & Math.), reported on the completed work: "The planar structure production method is based on thermal spraying of a gold film to a clearance of 30 µm
between two electrodes on a glass support. This process is carried out in ultrahigh vacuum under the pressure of 10 Torn As a result we get a metal film consisting of separate islets. Such structures are already well studied. In our case we studied not a simple metal film, but a composite ... Читать далее
