摘要：

A phosphor contains a crystal phase having a chemical composition Ce x M 3-x-y ² 6 ³ 11-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. ² contains Si in an amount of 50 mol% or more of a total mol of ². ³ contains N in an amount of 80 mol% or more N of a total mol of ³. x satisfies 0 <； x ‰¤ 0.6. y satisfies 0 ‰¤ y ‰¤ 1.0. z satisfies 0 ‰¤ z ‰¤ 1.0. The phosphor has a maximum peak of an emission spectrum in a wavelength range of 600 nm or more and 800 nm or less and a first peak of an excitation spectrum in a wavelength range of 500 nm or more and 600 nm or less.
