A new form of light

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

06-Oct-2016

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 ...
