Zusammenfassung:	To provide a production method of a crystal capable of producing a crystal of a comparatively large size and a uniform composition, and to provide a new single crystal phosphor obtained by the production method.SOLUTION: A single crystal phosphor contains a main component composed of YAG or LuAG and an accessory component containing at least one element of Ce, Pr, Sm, Eu, Tb, Dy, Tm, and Yb. A uniform concentration region where the accessory component is uniformly distributed is situated at the central part of the cross section of the single crystal phosphor and occupies an area of 35% or more to the area of the cross sectional.SELECTED DRAWING: Figure 2A 【課題】比較的に大きなサイズで、より均一な組成の結晶体を得ることができる結晶体の製造方法と、その製造方法により得られる新規な単結晶蛍光体を提供すること。【解決手段】ＹＡＧまたはＬｕＡＧから成る主成分と、Ｃｅ、Ｐｒ、Ｓｍ、Ｅｕ、Ｔｂ、Ｄｙ、ＴｍおよびＹｂの内少なくとも１つの元素を含む副成分と、を有する単結晶蛍光体である。単結晶蛍光体の横断面において、副成分が均一に分布する均一濃度領域が、横断面の中央部に位置し、横断面の断面積に対して、均一濃度領域の面積割合が、３５％以上である。【選択図】図２Ａ
