1,000 times more efficient nano-LED opens door to faster microchips


The electronic data connections within and between microchips are increasingly becoming a bottleneck in the exponential growth of data traffic worldwide. Optical connections are the obvious successors but optical data transmission requires an adequate nanoscale light source, and this has been ...


Merck and CLEARink Displays sign development agreement

Aim to commercialize video-capable, color-reflective displays


Merck announced that it has signed a comprehensive materials development agreement with CLEARink Displays, Inc., aiming to bring CLEARink’s innovative and patented reflective display technology to market by the end of 2017. Merck is a world leader in developing materials and formulations for the ...


Discovery of new crystal structure holds promise for optoelectronic devices


A Florida State University research team has discovered a new crystal structure of organic-inorganic hybrid materials that could open the door to new applications for optoelectronic devices like light-emitting diodes and lasers. Associate Professor of Chemical and Biomedical Engineering Biwu Ma ...

A new form of light

Scientists have discovered a method to create fluorescent light that may have promising applications


Glow-in-the-dark stickers, weird deep-sea fish, LED lightbulbs -- all have forms of luminescence. In other words, instead of just reflecting light, they make their own. Now a team of scientists from the University of Vermont and Dartmouth College have discovered a new way that some molecules can ...
