Phosphor and manufacturing method for the same, and light source

A manufacturing method of a phosphor, containing a phosphor crystal which is given by a general composition formula expressed by MmAaDbOoNn:Z, (wherein element M is at least one kind of element having bivalent valency, element A is at least one kind of element having tervalent valency selected from the group consisting of Al, Ga, In, Tl, Y, Sc, P, As, Sb, and Bi, element D is at least one kind of element having tetravalent valency, O is oxygen, N is nitrogen, and element Z is at least one kind of element selected from rare earth elements or transitional metal elements, and further containing fluorine or boron and fluorine expressed by m=a=b=1, and n=2/3m+a+4/3b−2/3o),

• said method comprising the steps of:
• weighing and mixing the raw materials in an inert atmosphere to manufacture a mixture;
• firing this mixture to manufacture a fired substance, and
• pulverizing this fired substance to manufacture the phosphor,
• wherein a fluorine compound or a boron compound and a fluorine compound are further added to a raw material for forming the phosphor expressed by the composition formula MmAaDbOoNn:Z.
