Tiny Tubes Break the Rules of Light

TL;DR;

Japanese scientists have discovered that carbon nanotubes can emit light with more energy than they absorb, a phenomenon called up-conversion photoluminescence, which defies conventional physics. This is due to tiny vibrations called phonons that give electrons an extra energy boost. Heating the nanotubes further enhances their glow, potentially leading to advancements in solar panels, laser cooling, and light-powered devices.
