摘要：
本发明目的为提供新型氧化物荧光材料。该荧光材料以下述元素为构成元素，所述元素为选自Mg、Ca、Sr、Ba中的元素，选自Si、Ge中的元素，选自稀土类的元素，以及氧；其结晶结构为假硅灰石结构。在基板51上层叠配置由荧光材料形成的膜54及含有选自Si、Ge中的至少一种或一种以上的元素作为构成元素的膜52。具有连接由荧光材料构成的部位、含有选自Si、Ge中的至少一种或一种以上的元素作为构成元素的邻接膜。
摘要（英）：

The present invention aims at providing a novel oxide fluorescent material. The novel oxide fluorescent material is a fluorescent material including: as constituent elements, at least one or more elements selected from the group consisting of Mg, Ca, Sr and Ba; at least one or more elements selected from the group consisting of Si and Ge; at least one or more elements selected from the group consisting of rare earth elements; and oxygen, wherein the crystal structure is a pseudowollastonite crystal structure. The fluorescent substance includes a layer 54 comprised of the fluorescent material and a layer 52 including at least one or more elements selected from the group consisting of Si and Ge, the layers stacked on a substrate 51. The fluorescent substance includes an adjacent layer that includes at least one or more elements selected from the group consisting of Si and Ge and is in contact with the portion constituted by the fluorescent material.
