Local linear compressibility of (MnF6)2− clusters in Mn4+-doped BaTiF6 red phosphor

Abstract The local linear compressibility of (MnF 6 ) 2− clusters in Mn 4+ -doped BaTiF 6 red phosphor is evaluated by analysing its pressure-induced R line red-shift. The result implies that this local linear compressibility is much smaller than the linear compressibility of host BaTiF 6 crystal as a whole. The causes of the difference of linear compressibility and the reasonableness of the local linear compressibility of (MnF 6 ) 2− clusters in BaTiF 6 : Mn 4+ crystal are discussed.
