Synthesis and photoluminescence properties of octahedral K2（Ge,Si）F6：Mn^4＋ red phosphor for white LED

A novel red-emitting K2（Ge,Si）F6：Mn^4＋ phosphor with uniform morphology was synthesized by co-precipitation method. The pure K2GeF6 phase with P63 mc space group other than P3m1 space group was affirmed just by incorporation of Si in K2GeF6 at room temperature according to XRD characterization. SEM...
