摘要：

Wannier-Mott (W-M) exciton is studied under the confinement of linear potential in a Spherical Quantum Dot (QD) with ionized donor hydrogenic impurity (IDHI). Using electric field excitonic transitions have been used to explore the optical properties of the above-said system. Time independent Schrodinger equation is solved numerically using effective mass approximation. The response of Absorption Coefficients (ACs) as a function of excitonic transition, electric field, and intensity of the laser field is investigated. Optical properties get drastically modified under confinement. The effect of IDHI is also studied in ACs for exciton in linear potential under spherical QD for the first time.
