TL;DR: In this article, the effects of the problem variables such as the core and shell sizes, the donor position in the structure and the pressure dependence of the physical parameters of the material have been analyzed.

TL;DR: In this paper, the effect of a magnetic field on the ground-state energy of a donor impurity confined in a polar CdSe spherical quantum dot embedded in a nonpolar matrix is studied theoretically.

TL;DR: In this paper, the effect of magnetic and electric fields on the ground-state energy of a donor impurity confined in a polar CdSe quantum nanocrystallite embedded in a nonpolar matrix was studied.

TL;DR: Using the effective mass approximation and a variational procedure, this article investigated the nonlinear optical absorption coefficient and the relative refractive index changes associated to a single dopant confined in core/shell quantum dots considering the influences of the core and shell dimensions, externally applied magnetic field, and dielectric mismatch.

TL;DR: In this article, the effects of temperature, pressure and size on the absorption coefficient and relative refractive index change associated with the $$1s-1p$$ inter-band transition of a spherical quantum dot were investigated.
