The recent advent of Lu3Al5O12:Ce optical ceramics marks a turning point in scintillator material technology. In this work, the optical investigations coupled with X-ray absorption near edge spectroscopy evidence the beneficial role of MgO sintering agent and Mg2+ co-dopants drive the partial converison of Ce3+ to Ce4+.
