Red phosphor BaSiF 6 :Mn 4+ has been synthesized by a hydrothermal method at 120°C for 24 h, in which either Si or SiO 2 is used as silicon source. HF as weak acid performs a complex agent for the formation of anion groups [SiF 6 ] 2− and [MnF 6 ] 2− . The luminescence properties of undoped BaSiF 6 have been firstly observed. The dependence of luminescence intensities of BaSiF 6 :Mn 4+ on the concentrations of HF and KMnO 4 in precursory solution has been investigated. The as‐prepared BaSiF 6 :Mn 4+ exhibits high chemical stability even in deionized water.
