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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
