How to predict the location of the defect levels induced by 3d transition metal ions at octahedral sites of aluminate phosphors

How the 3d transition metal (TM) ions induce defect levels in wide band gap compounds and how these defect levels evolve from compound to compound is very important in understanding and predicting the luminescent properties of TM activated phosphors. This issue is discussed by studying the ground state 3dⁿ level locations of the TM...
