Quantum-defect diamond (IMAGE)
Caption
When a green laser shines on a special kind of diamond with atomic-scale defects, it can cause it to fluoresce red. This process is depicted in this photo of a quantum diamond sample as it was struck by the light of a green laser pointer, with a red light filter added to half of the sample to reveal the red fluorescence.
