Abstract
A red phosphor is provided, comprising an inorganic luminescent compound represented by formula (1) having an emission spectrum resolvable into a first Gaussian emission curve and a second Gaussian emission curve; wherein the first Gaussian emission curve has a first Gaussian emission curve peak, P; wherein the first Gaussian emission curve peak, P, has a peak 1 height, H, a peak 1 peak wavelength, Pλ, and a peak 1 area, A; wherein the second Gaussian emission curve has a second Gaussian emission curve peak, P; wherein the second Gaussian emission curve peak, P, has a peak 2 height, H, a peak 2 peak wavelength, Pλ, a peak 2 full width at half max, FWHM, and a peak 2 area, A; wherein Pλ<Pλ; and, wherein the peak 2 full width at half max, FWHM, is minimized.
