Abstract
A 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, P1; wherein the first Gaussian emission curve peak, P1, has a peak 1 height, HP1, a peak 1 peak wavelength, PλP1, and a peak 1 area, AP1; wherein the second Gaussian emission curve has a second Gaussian emission curve peak, P2; wherein the second Gaussian emission curve peak, P2 has a peak 2 height, HP2, a peak 2 peak wavelength, PλP2, a peak 2 full width at half max, FWHMP2, and a peak 2 area, AP2; wherein PλP1<PλP2; and, wherein, at least one of, the peak 2 height, HP2, the peak 2 full width at half max, FWHMP2, and, the peak 2 area, AP2, is minimized.
