we report a synthetic technique and a formation mechanism for obtaining red phosphors BaSiF6:Mn4+ by etching Si/SiO2 under hydrothermal condition. The luminescence properties of undoped BaSiF6 have been firstly observed. A significant improvement in luminescence efficiency of BaSiF6:Mn4+ has been obtained by optimizing synthetic techniques. The as-prepared BaSiF6:Mn4+ exhibits high chemical stability in ion-free water. The understanding of formation mechanism of BaSiF6:Mn4+ obtained from Si/SiO2 is fundamentally important, which might be extended to other Mn4+ doped rare earth alkaline complex fluorides phosphors with controlled growth kinetics for advanced properties.
