摘要：
Colloidal InSb-based quantum dots (QDs) without shells and with InP, CdS, InP/CdS, and InP(Cd)/CdS shells were synthesized and studied. The best characteristics of photoluminescence and its stability were obtained for InSb core/shell QDs with InP(Cd)/CdS two-layer shell. The obtained results are explained in the framework of models of the excitonic recombination mechanism and the electron quantum confinement of a QD core by an isomorphous two-layer shell.
