|Abstract:||Photoluminescence (PL) and Raman spectroscopies of CdSeZnS core/shell quantum dots (QDs) were studied under hydrostatic pressure (0-160 kbars) at room temperature. Two phase transitions, at 69 and 79 kbars, respectively, were observed, which correspond to wurtzite-rocksalt and rocksalt-cinnabar structural transformations. The full width at half maximum of PL peaks was found to decrease anomalously approximately 30% with pressure. These experimental data show significant difference between the CdSeZnS core/shell QDs and simple bare CdSe QDs or bulk CdSe, implying the ZnS shell plays a dominant role in structural stability and electronic state of such system. © 2007 American Institute of Physics.|
