MgTiOF:Mn for deep red emission using a pressure vessel is investigated. The formation of a luminescent phase was not confirmed. Since the Mn4+ emission was confirmed from PL, a slight MgTiOF-based phase was formed, and it is considered possible to control by adjusting the amount of HF to be added.
