Metallic gels produce tunable light emission

September 3, 2015

Researchers at MIT have developed a family of materials that can emit light of precisely controlled colors — even pure white light — and whose output can be tuned to respond to a wide variety of external conditions. The materials could find a variety of uses in detecting chemical and biological compounds, or mechanical and thermal conditions.

The material, a metallic polymer gel made using rare-earth elements, is described in a paper in the Journal of the American Chemical Society by assistant professor of materials science and engineering Niels Holten-Andersen, postdoc Pangkuan Chen, and graduate students Qiaochu Li and Scott Grindy.
