AbstractThe spin Hamiltonian parameters (zero-field splitting D, g factors and hyperfine structure constants) and local structure as well as their concentration dependences for Cd1-xMnxS quantum dots are theoretically investigated from the perturbation formulae of these parameters for a 3d(5) ion under trigonally distorted tetrahedra. The impurity Mn2+ is found not to occupy exactly the host Cd2+ site in the CdS quantum dots but to experience an inward displacement 0.041 angstrom towards the ligand triangle along the C-3-axis because of the size mismatching substitution and the internal stress. As compared with bulk CdS : Mn2+, the larger impurity displacement and stronger Mn2+ 3d-3s orbital admixture in the Cd1-xMnxS quantum dots suitably account for the higher zero-field splitting and hyperfine structure constant, respectively. The impurity axial displacement and the Mn2+ 3d-3s orbital admixture in the Cd1-xMnxS quantum dots may exhibit an approximately cubic increase with increasing the Mn concentration x from 0.001 to 0.15.
