Large ground-state dipole moments were obsd., esp. for the smallest crystals. In these, the authors found a very large anisotropy of the absorption and most of the dipole strength is along the direction of the ground-state dipole moment. For the anisotropy, the authors propose a mechanism for intensity borrowing from intraband transitions, induced by the field of the ground-state dipole moment.Electronic transition (intraband; in linear dichroism ofCdSe nanocrystal with large anisotropy of band-gapabsorption induced by ground-state dipole moments)DichroismNanocrystalsOptical absorptionOpticalanisotropy (linear dichroism of CdSe nanocrystal with large; anisotropy of band-gap absorption induced by ground-state; dipole moments)UV and visible spectra (of linear dichroism; of CdSe nanocrystal with large anisotropy of band-gap; absorption induced by ground-state dipole moments)cadmium selenide nanocrystal visible dichroism anisotropyband gap absorptionabsorption induced by ground-state dipole moments)text::journal::journal article::research article
