University of Innsbruck: New LED phosphor saves energy

Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which in turn can significantly improve the energy efficiency of lighting systems.

Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes. "In a white LED, red and yellow-green phosphors are excited by the light from a blue diode. The particles emit light in the red and green range, and in combination with the blue light they produce white light," says Hubert Huppertz from the Department of General, Inorganic and Theoretical Chemistry at the University of Innsbruck, Austria, explaining how it works. He and his team are working on improving the red and green phosphors. In cooperation with OSRAM Opto Semiconductors, his team has now succeeded in synthesizing a new red phosphor that has excellent luminescence properties and can make LED lighting significantly more energy-efficient.

OSRAM Opto Semiconductors, a strong industrial partner, the Fraunhofer Institute for Microstructures of Materials and Systems IMWS in Halle and Dirk Johrendt's research group at the Ludwig Maximilian University in Munich were also involved in further characterizing the new material. The development has already been registered for patent.

Siemens Mobility has put a new robot-controlled frame welding facility into operation in Graz.

Austria on track to implement the mobility of the future

Recently the first autonomous or self-driving bus was put into operation in Vienna, and the first autonomous air taxi in Austria should be ready for series production by 2020. It seems that the mobility of the future has long begun in the Alpine Republic. This is, last but not least, evidence of the ideal conditions which innovative companies benefit from here.
