Abstract:
CdTe quantum dots coated with a silica layer containing CdS-like clusters exhibit intense photoluminescence and a spectral red-shift. Biexciton Auger recombination of these particles is examined by transient absorption spectroscopy. A lengthening of the Auger recombination lifetime by a factor of ∼3.5 in the presence of the CdS-like clusters is observed and may contribute to the good PL properties of these nanostructures.
