Simultaneous effect of the capped matrix and the geometric factors of CdS/ZnSe spheroidal quantum dots on the linear and nonlinear optical properties
In this description, we have numerically studied and modulated the transition energy, the linear and third order nonlinear absorption coefficient as well as the refractive index changes under the effective mass approximation and the compact density matrix formalism in (CdS/ZnSe) core/shell prolate s...

| description | In this description, we have numerically studied and modulated the transition energy, the linear and third order nonlinear absorption coefficient as well as the refractive index changes under the effective mass approximation and the compact density matrix formalism in (CdS/ZnSe) core/shell prolate spheroid quantum dot (CSPSQD), incorporated in dielectric matrices as SiO

, PVC and PVA. Our results proved that the linear and nonlinear optical proprieties are sensitive by the geometry of the quantum dots (QDs) and the surrounding medium. The results shows, when the eccentricity increase, the transitions energy decrease considerably and the resonance peaks positions towards low energies. The suitable choice of the dielectric matrix and the geometrical size offers the possibility of tuning the optical properties of the QDs which are important of optoelectronic and photonic devices. |
