DOI: 10.1002/advs.78120 Researchers at Umea university thought gold particles would make electronic components emit more light. Instead, they discovered an unexpected effect that could be important for the future of organic electronics.

The project that led to the discovery, now published in Advanced Science , emerged from a collaboration between two research groups. Research leaders Nicolò Maccaferri and Ludvig Edman recognized that they could benefit from each other's complementary expertise. One wanted to better understand the dynamics of electrochemical reactions in organic electronic devices, while the other was looking for ways to improve device performance.
