Triboluminescence flashes from high-speed ruptures in carbon nanotube Macro-Yarns
2018
© 2017 During tensile tests of carbon nanotube (CNT) macrostructures (ribbons, ropes and tows) under dynamic strain rates (1000 s –1 ), we recorded temporally sporadic, spatially localized visible light emissions ("flashes") of less than 1.5 µs duration. The flashes occurred at the fracture sites and were, depending on the sample morphology, either distributed randomly over time (for tows) or occurred all at once over larger areas of several pixels (for ribbons).
