Phosphor and manufacturing method for the same, and light source

A phosphor comprising:

• a product phase
• expressed by a composition formula MADOoNn:Z, where element M is at least one or more kind of element having bivalent valency, element A is at least one or more kind of element having tervalent valency, element D is at least one or more kind of element selected from the elements having tetravalent valency, O is oxygen, N is nitrogen, and element Z is at least one more kind of element selected from rare earth elements or transitional metal elements satisfying n=3-2/30, o+n>8/3, and
• showing a diffraction peak with relative intensity of 10% or more in the Bragg angle (2θ) range from 36.5° to 37.5° and from 41.9° to 42.9° of the X-ray diffraction pattern, when the relative intensity of the diffraction peak having a highest intensity in a powder X-ray diffraction pattern by CoKα ray is defined as 100%,
• wherein
• a crystal lattice volume of the product phase is 280.5 Å3 or more.
