P-179L: Late-News Poster: Chemical Stability Enhancement of K2SiF6:Mn4+ by Metal (Oxide) Coating

The K2SiF6:Mn4+ phosphor was synthesized by a redox reaction from SiO2 [1]. Under the 450 nm excitation, K2SiF6:Mn4+ show a narrow deep‐red emitting around 633 nm which attributed to the 2Eg to 4A2g transition of Mn4+ ion with the half width of 8 ‐10 nm. The particle size was approximately 8 μm. We...
