Researchers at National Yang Ming Chiao Tung University announced a new non-toxic, metal-free light-emitting silicone that produces blue fluorescence when mechanically stressed, a development they said could advance glasses-free 3D displays and wearable imaging sensors. The research was published on May 6 in the journal JACS Au, and the work was carried out in collaboration with a team at Osaka Institute of Technology, the university stated.
