Sublattice resolution structural and chemical analysis of individual CdSe nanocrystals using atomic number contrast scanning transmission electron microscopy and electron energy loss spectroscopy
Article Abstract:
The atomic column-resolved atomic number contrast scanning transmission electron microscopy (Z-STEM) image provides information both on lateral shape of the nanocrystal and also relative thickness of the individual atom columns from a single image. The three-dimensional model is developed to analyze different nanocrystals observed in different orientations.

CdSe/CdS/ZnS and CdSe/Znse/ZnS core-shell-shell nanocrystals
Article Abstract:
The synthesis and characterization of highly luminescent colloidal nanocrystals consisting of CdSe cores protected with double inorganic shells is presented. The outer ZnS shell provides efficient confinement of electron and hole wave functions inside the nanocrystal as well as high photochemical stability.

Ultrafast carrier dynamics in CdSe nanocrystals determined by femtosecond fluorescence upconversion spectroscopy
Article Abstract:
Femtosecond fluorescence upconversion spectroscopy is utilized to probe the dynamics of photogenerated excitons in high quality CdSe nanocrystals. A new model describing mechanisms of exciton relaxation in CdSe quantum dots is presented.
