Scholarcy highlights

  • Hot electrons in semiconductors lose their energy very quickly to lattice vibrations
  • We report slow intraband relaxation in colloidal quantum dots
  • The shell is terminated by a cadmium selenide passivating layer to remove electron traps and is covered by ligands of low infrared absorbance at the intraband energy
  • We found that relaxation is markedly slowed with increasing zinc selenide shell thickness
