Samsung reported that two of the company’s research fellows have proved the potential of QLEDs for commercial purposes in a new study, which was published in ‘Nature’ on November 27, 2019. The research team managed to hugely improve quantum efficiency, as well as extend the lifetime of the QLED element by improving the structure of quantum dots. With the thick shell structure proposed by the research team, oxidation of the core and energy leak could be prevented. The study concluded that the method had improved quantum efficiency by 21.4% and increased the ...

The on-going development of LED research and bioelectronics medicine has sparked off a new solution for curing bladder problems. A team consisting of researchers from Washington University School of Medicine, the University of Illinois and Northwestern University has created an implantable device with biointegrated LEDs that can detect and tamp overactivity in the bladder. The research team of neuroscientists and engineers introduced a miniaturized bio-optoelectronic device that is soft and stretchy and implanted it around the bladder of the lab rats. The device expands ...
