The present invention relates to a process for producing an eu2 + activated inorganic red phosphor, wherein the phosphor exhibits a luminescent spectrum decomposable by a first Gaussian emission curve and a first Gaussian emission curve; The first Gaussian emission curve has a first gaussian emission curve peak, p1; A first Gaussian emission curve peak, p1 has a peak height of 1, hp1, a peak one peak wavelength, p? P1, and a peak 1 area, ap1; The second Gaussian emission curve has a second Gaussian emission curve peak, p2; The second Gaussian emission curve peak, p2 has peak 2 height, hp2, peak 2 peak wavelength, p? P2, peak 2 half full width, fwhmp2, and peak 2 area, ap2; Where p? P1 <p? P2; Peak 2 half full width, fwhmp2 is minimized. |
