The perturbation approach and variational method were used in calculations under Effective Mass Approximation. The considered structure is embedded in a variable polymer matrix. The binding energy (BE), photoionization cross-section, polarizability, and diamagnetic susceptibility of the excited impurity were calculated first according to the core/shell radius ratio and then under a significant external electric field and in the absence of an external electric field. A significant stark shift was observed in the BE relative to the embedded matrix element.en10.1016/j.physb.2023.415458info:eu-repo/semantics/closedAccessSemiconductorCore/shell quantum dotsBinding energyStark effectDiamagnetic susceptibilityArticle6722-s2.0-85175731545Q2WOS:001110815000001Q2
