The energy levels of Mn d-electrons in ZnS : optical properties Zns: Mn

The goal of the project is to obtain a reasonably accurate placement of the electronic energy levels of the "d electrons" of Mn relative to the valence band and "d electron" energies in the host crystal ZnS. This will contribute to an understanding of the process which governs the luminescence of ZnS: Mn. By adjusting the degree of ionicity or covalency to make the crystal field splitting approach to its measured value, an estimate can be made of the position of the ground state of the Mn2+ 3d electrons relative to the valence band of the ZnS host crystal.
