Abstract: A phosphor contains a crystal phase having a chemical composition CexM3-x-yβ6γ11-z. M is one or more elements selected from the group consisting of Sc, Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. β contains Si in an amount of 50 mol % or more of a total mol of β. β further contains Al. γ contains N in an amount of 80 mol % or more N of a total mol of γ. x satisfies 0

Abstract: A wavelength conversion member includes a substrate, a dichroic mirror layer, an SiO2 layer, a ZnO layer, and a phosphor layer, which are sequentially stacked from the substrate. The dichroic mirror layer reflects at least part of light incident from the above. The phosphor layer includes a plurality of phosphors and ZnO between the phosphors.
