Fluorescence limitations overcome by engineering light–matter interactions

The process by which pixels fluoresce in electronic displays uses energy highly inefficiently. The identification of fluorescent molecules with an unusual order of excited states opens up a fresh approach to tackling this issue.

Are you reading this News & Views article on a mobile phone? Do you stream your favourite series on a bright, flat-screen television, or help your kids do schoolwork on their tablets? If so, then one day you might benefit from the advance reported by Aizawa et al.1 in Nature. They describe a breakthrough that overcomes long-standing constraints imposed by the laws of quantum mechanics on the energy efficiency of electronic displays, using a new strategy for understanding and engineering the interactions of light with matter.
