The interband and intraband spectra of colloidal II-VI CdS and CdSe quantum dot cores and CdS/ZnSe, CdS/CdSe, CdSe/CdS, and CdSe/ZnSe core/shell systems are reported. Infrared absorption peaks between 0.5 and 0.2 eV are observed. The slope of the intraband energy versus the first interband absorption feature is characteristic of the relative band alignments of the materials constituting the core and the shell and it is analyzed within an effective mass model. The analysis provides a new estimate of the band gap of zinc blende CdSe as well as the band offsets in zinc blende and wurtzite CdSe, CdS, and ZnSe.
