Abstract
Provided is a phosphor, which is excited by a wide band of visible light, capable of emitting near-infrared light of high intensity. The phosphor comprises a crystal phase represented by a formula (1): MCuSiO(where M comprises one or more of Ba, Sr and Ca), and a crystal phase represented by a formula (2): MCuSiO(where M comprises one or more of Ba, Sr and Ca), wherein a ratio β of a diffraction peak intensity of MCuSiOwith respect to a diffraction peak intensity of MCuSiOin an X-ray diffraction (XRD) pattern obtained by powder XRD measurement using CuKα rays is 0<β≤0.50.
