PROBLEM TO BE SOLVED: To provide a phosphor having good temperature characteristics. A phosphor having a composition represented by the following composition formula (A), which exhibits an emission peak at a wavelength of 580 nm to 700 nm when excited by light having a wavelength of 250 nm to 500 nm. In X-ray diffraction using CuKα characteristic X-rays (wavelength 1.54056Å), diffraction angles (2θ) of 8.60 to 8.64 °, 11.16 to 11.20 °, 18.26 to 18.30 ° Simultaneously exhibit a diffraction peak. MAlSiON (A) (In the composition formula (A), M is Sr, and at least 0.1 mol% thereof is substituted with Eu.) [Selection figure] None |
