Research scientists at INM - Leibniz-Institute for New Materials have developed luminous particles that can also withstand high temperatures. When activated by UV light or x-rays, they glow orange red.
Everyone knows the small UV lamps at cash desks in supermarkets. They are used to verify whether “big banknotes” are genuine. To do so, colorful snippets light up inside the note. The luminous particles which cause this consist of organic compounds.
They are not suitable for high temperatures because, in such cases, the luminous particles disintegrate. They therefore cannot be used to provide counterfeiting protection for objects that are subjected to high temperatures.
Now research scientists at INM – Leibniz-Institute for New Materials have developed luminous particles that can also withstand high temperatures. When activated by UV light or x-rays, they glow orange red.
The researchers will be presenting their results from 25 to 29 April 2016 in Hall 2 at the stand B46 of the Hannover Messe in the context of the leading trade fair for R & D and Technology Transfer.
Engine components in cars, high-grade machinery for the industrial sector or high-value appliances in private households – some of these everyday objects are subjected to high temperatures when used. Original automotive components and the corresponding spare parts are a seal of quality for manufacturers and consumers:
For the driver, original components mean that the risk of accident is lower. Originality of the parts can only be proven, if the counterfeit protection also withstands high temperatures and can be read easily. A missing counterfeit protection on forged spare parts guards the original manufacturer from claims for compensation.
“For our luminous pigments, we can achieve such temperature stability up to 600 degrees Celsius,” says INM’s Peter William de Oliveira. The developers at INM have succeeded in doing so by using a manufacturing method applying wet chemical processes.
“The particles not only fulfill the demands of high temperatures but through the addition of suitable solvents, they can also be converted into printable paste. Consequently, they can easily be printed onto many materials using screen printing, for example,” the Head of the InnovationCenter at INM explains further.
Using luminous pigments made of yttrium oxide or gadolinium oxide, printed designs are created in white or transparent that glow orange red in UV light or x-rays. With different manufacturing conditions, particles of between seven and approximately 600 nanometers can be achieved thus alloying the researchers to take different requirements and processes in industry into account.

INM conducts research and development to create new materials – for today, tomorrow and beyond. Chemists, physicists, biologists, materials scientists and engineers team up to focus on these essential questions: Which material properties are new, how can they be investigated and how can they be tailored for industrial applications in the future? Four research thrusts determine the current developments at INM: New materials for energy application, new concepts for medical surfaces, new surface materials for tribological systems and nano safety and nano bio. Research at INM is performed in three fields: Nanocomposite Technology, Interface Materials, and Bio Interfaces.
INM – Leibniz Institute for New Materials, situated in Saarbrücken, is an internationally leading center for materials research. It is an institute of the Leibniz Association and has about 220 employees.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
