Changing Frequency Speeds Phosphor Light Emission
PROVIDENCE, R.I., Nov. 4, 2015 — A technique for controlling light from phosphors at very high speeds could overcome the materials' slow optical performance, potentially enabling their use in optical communications. Phosphors are common light emitters used in light bulbs, LEDs and elsewhere. While they are extremely efficient, they can't be turned on and off very quickly, which has essentially prohibited their use in applications where rapid optical modulation is required. Now researchers from Brown and Harvard
