Abstract: An emission spectrum of a manganese-doped red fluoride phosphor includes a zero phonon line crest and a crest. The zero phonon line crest has a first peak emission wavelength and a first intensity (I1). The crest has a second peak emission wavelength and a maximum intensity (Imax) except for the zero phonon line crest. The second peak emission wavelength is greater than the first peak emission wavelength. A ratio (I1/Imax) of the first intensity (I1) to the maximum intensity (Imax) is ranged from about 0.2 to about 8 such that a luminous decay time of the manganese-doped red fluoride phosphor is less than 10 ms.
