Abstract

We report exciton spin relaxation dynamics in colloidal wurtzite and zinc blende CdSe quantum dots measured using ultrafast cross-polarized heterodyned transient grating spectroscopy. The zinc blende (cubic base) quantum dots have a simpler fine structure as compared to wurtzite (hexagonal base) due to differences in the crystal field splitting. Faster exciton spin relaxation dynamics are observed in the zinc blende quantum dots.
