A new Rb2SiF6:Mn4+ phosphor has been successfully synthesized through a one-step co-precipitation method. The addition of H2O2 into the solution with appropriate reaction temperature results in the reduction of Mn7+ to Mn4+. Mn4+ is excited by UV and blue light, providing sharp red emission at approximately 630 nm. Rb2SiF6:Mn4+ has a Fm3m (225) cubic phase crystal structure as determined using X-ray diffraction and Total Pattern Analysis Solutions. No apparent impurity phase is found in the X-ray diffraction spectrum. All luminescence properties, namely, emission, excitation, and thermal luminescence spectrum, have been investigated in depth.
