Slow emitters transformed into fast light sources

22 octubre 2015

Phosphors are efficient light emitters but they’re not optimal for high-speed communications because they turn on and off slowly. Researchers have now found a way to modulate light from phosphor emitters three orders of magnitude faster using phase-change materials, which could make phosphors useful in a range of new optoelectronic applications.
