Abstract
A phosphor composition and a light source constructed therefrom are disclosed. The phosphor composition includes first and second phosphors. The first phosphor includes first phosphor particles that convert light of an excitation wavelength to light having a first spectrum characterized by an intensity of light that varies as a function of wavelength. The first phosphor particles are chosen such that the first spectrum is independent of the size of the particles. The second phosphor includes particles of a QD phosphor that convert the excitation light to light in a QD phosphor spectrum. The first phosphor particles and the QD phosphor particles are present in a ratio of concentrations. The ratio, the first phosphor particles, and the QD phosphor particles are chosen such that a combined spectrum has an intensity that is more uniform as a function of wavelength than either the QD phosphor spectrum or the first spectrum.
