Discovery: A New Form of Light

University of Vermont doctoral student Morgan Cousins holds up a sample of a solution of strange rotor molecules made from boron-based dye. Led by UVM chemistry professor Matt Liptak (on left), she was part of a team that tested the dye and discovered how the molecules can release a bright fluorescent glow--it's a new method to create light. The new light may have many promising applications including novel kinds of LED bulbs and medical imaging. Their results were published in the journal Nature Chemistry. Credit: Joshua Brown

Glow-in-the-dark stickers, weird deep-sea fish, LED lightbulbs – all have forms of luminescence. In other words, instead of just reflecting light, they make their own...

Germanium defects in a diamond crystal lattice act as a reliable source for single photons. Pure diamonds are naturally colorless, but gaps in the crystal structure or impurities of other elements can create colors and even emit fluorescence. Recently, researchers have shown that the fluorescent lattice defects could be useful as single photon sources for quantum cryptography and as bright luminescent makers in living cells.

Now a new type of diamond crystal defect that fluoresces to produce single photons in a narrow, high energy wavelength band has been demonstrated...
