Spin blockade and phonon bottleneck for hot electron relaxation observed in n-doped colloidal quantum dots

Hot electrons in bulk semiconductors usually relax via electron-phonon scattering on a sub-picosecond timescale. Here, the authors observe hot electron lifetime as long as 320 picoseconds by performing a photochemical reduction reaction on colloidal quantum dots.
