In this paper, we studied the role of the crystal structure in spheroidal CdSe nanocrystals on the band-edge exciton fine structure. Ensembles of zinc blende and wurtzite CdSe nanocrystals are investigated experimentally by two optical techniques: fl

This work uncovers the thermal properties of colloidal CdSe/CdS quantum dots (QDs) associated with additional epitaxial strain at the core/shell interface. We investigate the temperature-dependent behavior of the longitudinal optical (LO) phonon freq

We investigate the encapsulation of CdSe/CdS quantum dots (QDs) in a silica shell by in situ Raman spectroscopy and find a distinct shift of the CdS Raman signal during the first hours of the synthesis. This shift does not depend on the final silica

We report on the “flash” synthesis of CdSe/CdS core–shell quantum dots (QDs). This new method, based on a seeded growth approach and using an excess of a carboxylic acid, leads to an isotropic and epitaxial growth of a CdS shell on a wurtzite C

We investigate the interface between core and shell in zinc blende CdSe-based CdSe/CdS dot-in-dot heteronanocrystals. Using X-ray diffraction and transmission electron microscopy, we show that a CdS shell grows coherently around the CdSe core. A comp
