UVB LEDs for medical phototherapy

PhotonicsView, October/November 2019

Phototherapy involves exposure of the skin to light in order to treat various skin diseases such as psoriasis. In the 20th century, great advancements have been made in developing safe and effective narrowband ultraviolet B (NB‐UVB) phototherapy modalities. Targeted phototherapy delivers light exclusively to the affected skin and thereby avoids side effects on unaffected healthy areas. Recently, solid‐state UV light emitting diodes (UV LEDs) have the potential to become the light source of the future for targeted NB‐UVB phototherapy treatments.

Research realizes innovation in fabricating reflective coatings for high-power UV optics

LEDs Magazine, October 2019

A consortium of optics researchers describes a new method for fabricating ultraviolet optics that leverages a metallic intermediate layer on a plastic-coated aluminum reflector to increase stable lifetime operation under high-power UV LED irradiation.

In the study, OSA Opto Light's R&D team demonstrates that by applying a metallic intermediate layer such as a combination of copper (Cu) and nickel (Ni) with a thickness greater than 30 µm, it is possible to dramatically reduce the maximum temperature of the reflector — in this experiment, from 117°C to 51°C — and obtain long-term stability over 5000 hours under high-power irradiation from UV LEDs.

Work Group Aluminiumnitrid: Launch of a new sublimation growth laboratory at the IKZ

IKZ News, August 2019

Leibniz Institute for Crystal Growth

In 2019, the Aluminium Nitride group launched a new crystal growth laboratory with three identical reactors for the sublimation growth of aluminium nitride monocrystals. This measure not only increases the growth capacity significantly, but also helps to guarantee reproducible growth conditions from test to test or plant to plant, even from an industrial point of view, i.e. within a very narrow parameter range.

Hygienic beer caps thanks to Fraunhofer technology

Fraunhofer IOSB, Branch Advanced System Technology - Research News, August 2019

Advanced System Technology Branch of Fraunhofer Institute of Optronics, System Technologies and Image Exploitation

UV light inactivates germs in drinking water. Until now, the disinfection process relied on mercury-vapor lamps, which emit light in the UV spectrum. However, mercury is a heavy metal that affects human health and the environment. Fraunhofer researchers are investigating a greener and more efficient alternative, which uses UV LEDs to destroy bacterial DNA. The technology is also suitable for disinfecting brewing water and for disinfecting the caps for bottled beer, soft drinks, and mineral water during the filling process.

Understanding limitations in deep UV LEDs

Compound Semiconductor, March 2019

Researchers at TU Berlin have identified a fall in carrier-injection efficiency as a significant contributor to the decline in efficiency of the deep UV LED as its emission is stretched to shorter wavelengths.
The team’s insight promises to aid attempts to increase the optical efficiency of these emitters, which are used for medical diagnostics and the sensing of gases such as nitrogen monoxide.

Ultra versatile

OSRAM ON Magazine, 18.02.2019

Many people associate ultraviolet (UV) light with an unpleasant sunburn. But this short-wave radiation has the capacity to solve important problems of the future. Providing clean water has enormous potential for the future. For water treatment they need the right radiation at the right place in the right amount. UV LEDs not only make this possible for large volumes but also save energy. The members of the Advanced UV for Life consortium are also exploring applications in medicine, such as effective disinfection strategies to combat multi-resistant bacteria and phototherapy treatments for skin disorders. Other areas of research include the targeted control of plant metabolism to enrich specific substances, and industrial curing processes.
