The coming disruption of OLED technologies

Organic light-emitting diodes (OLEDs) will soon show our world in a new light: the days of small light sources are numbered; in future, entire walls, ceilings, façades and car exteriors will light up our lives. Empa is exploring ...

Rotating molecules create a brighter future

Scientists have discovered a group of materials which could pave the way for a new generation of high-efficiency lighting, solving a quandary which has inhibited the performance of display technology for decades. The development ...

The repulsion trick: A self-solving puzzle for organic molecules

Jülich researchers have succeeded in controlling the growth of organic molecules using a special trick. Molecules that repel each other play a key role in this process: due to their opposing forces, they always keep a certain ...

Boosting the lifetime and effectiveness of biomedical devices

Modern electronic biomedical devices are enabling a wide range of sophisticated health interventions, from seizure detection and Parkinson's disease therapy to functional artificial limbs, cochlear implants, and smart contact ...

Materials that emit rainbows

Mechanochromic luminescent (MCL) materials change their color in response to a change in their environment, like pressure and temperature. To date, most MCL materials only change between two colors, limiting their applications. ...

Researchers achieve major breakthrough in flexible electronics

Semiconductors, which are the very basic components of electronic devices, have improved our lives in many ways. They can be found in lighting, displays, solar modules and microprocessors that are installed in almost all ...

Protecting dark skies for astronomy and life

Artificial light at night is a threat to astronomical research, personal safety, and the health of both humans and wildlife. The problem is worsening with the proliferation of LED billboards and blue-rich white light LEDs ...
