Moscow scientists develop new quantum dots based graphic data storage

Moscow scientists develop new quantum dots based graphic data storageScientists at Moscow Lomonosov State University have used quantum dots to create ?intelligent? liquid crystals, a potential solution for storing graphic data.

Moscow Lomonosov State University (MSU) announced earlier this week that its scientists have used quantum dots to create ?intelligent? liquid crystals. The results of the research have been published in Advanced Materials. According to MSU, one can inscribe an image on the new liquid crystals using ultraviolet, and then read the data by scanning the crystals with the same UV and recording changes in the polarization of light emitted by the new material. Liquid crystals possessing such a property can be potentially developed into devices to save, store and replay graphic data. MSU?s project developers believe that photo- and electricity-controlled liquid-crystal materials may one day become a source of single photons for quantum cryptography, and might also be used in nanophotonic systems, for example, to create very small lasers with low lasing threshold and with photo- and electricity-controlled emission characteristics...
