Carbon nanotubes release more energetic light than they receive, could help solar power
SMRTR summary
Carbon nanotubes can emit higher-energy light than they absorb, a phenomenon called up-conversion photoluminescence. RIKEN researchers discovered this occurs efficiently even in pristine nanotubes, not just those with defects. The process involves excitons absorbing energy from phonons, potentially boosting solar panel performance by converting infrared light to visible light.
