Current white light sources, such as LEDs, tend to oscillate between different color variations, which distorts the perception of the human eye. This limitation can be very disabling, even dangerous, during surgery or in the work of graphic designers and artists.

Researchers from the Center for Molecular Biophysics and the University of Michigan (United States) have developed a new system, based on dysprosium atoms and metallacrowns, which gives exactly white light that does not vary with conditions wear or temperature.

This work has been published in the Journal of the American Chemical Society.
