Phosphors are efficient light emitters but they're not optimal for high-speed communications because they turn on and off slowly. Researchers from Brown and Harvard have now found a way to modulate light from phosphor emitters three orders of magnitude faster using phase-change materials (VO2, in this case), which could make phosphors useful in a range of new optoelectronic applications.
