METHOD OF MAKING EU2+ ACTIVATED INORGANIC RED PHOSPHOR

摘要

A method of manufacturing an Eu²⁺ activated inorganic red phosphor is provided, wherein the phosphor exhibits 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, H_P1, a peak 1 peak wavelength, Pλ_P1, and a peak 1 area, A_P1; 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, H_P2, a peak 2 peak wavelength, Pλ_P2, a peak 2 full width at half max, FWHM_P2, and a peak 2 area, A_P2; wherein Pλ_P1Pλ_P2; and, wherein the peak 2 full width at half max, FWHM_P2, is minimized.
