A team of physicists headed by Prof. Sebastian Reineke of TU Dresden developed a new kind of storing information in fully transparent plastic foils. Their innovative idea is now published in the renowned online journal “Science Advances”.

Prof. Reineke and his LEXOS team work with simple plastic foils with a thickness of less than 50 µm, which is thinner than a human hair. In these transparent plastic foils, they introduced organic luminescent molecules. In the beginning, these molecules are in an inactive, dark state. Using ultraviolet irradiation, it is possible to turn this dark state locally into an active, luminescent one. By mask illumination or laser writing, activated patterns can be printed into the foil having a resolution comparable to common laser printers. Similar to glow-in-the-dark stickers, the patterns can be brought to shine and the imprinted information can be read out. By illuminating with infrared light, the tag is erased completely and new data can be written into it.

On 27 September 2018, the Excellence Commission announced the decision on the newly funded clusters within the framework of the Excellence Strategy. The Center for Advancing Electronics Dresden (cfaed) is a research cluster that has already been funded for one funding period within the previous Excellence Initiative and it looks back on many scientific successes from 2012-2018. cfaed has also played a decisive role in strengthening the attractiveness of the location for the local electronics industry and for new developments. With a newly adjusted research program, cfaed planned to build on these results in a second funding period and to follow up on many of the first successes, to lead to further breakthroughs and to link up with the newly added research fields of the program.
