Characterization of Excited-State Magnetic Exchange in Mn2+-Doped ZnO Quantum Dots Using Time-Dependent Density Functional Theory

Absorption spectra of Mn2+-doped ZnO quantum dots have been studied with the linear-response time-dependent density functional theory. Spectral changes caused by excited state dopant-carrier and dopant–dopant magnetic exchange couplings are investigated. The excitonic transition maximum shifts to hi...
