Bright Trion (IMAGE) University of Maryland Caption A UMD-led team of researchers has developed a method to trap trions at room temperature in single-walled carbon nanotubes. In this photoluminescence spectroscopy image, trapped trions and excitons can be seen as bright red spots against the dark blue background emissions from the host nanotube. This new work makes it possible to manipulate quasiparticles such as trions and study their fundamental properties in ways that have never been possible before.
