K2TiF6:Mn(4+) red phosphors with different Mn(4+) doping concentrations were obtained using the co-precipitation method. X-Ray diffraction, scanning electron microscopy, Raman spectra, Fourier transform infrared spectroscopy, photoluminescence excitation and emission spectra and decay curves were used to characterize the properties of K2TiF6:Mn(4+) phosphors. Under excitation at 470 nm, an intense red emission peak around 631 nm corresponding to the (2)E(g)-(4)A2 transition of Mn(4+) was observed for 2.48 mol
