摘要：
本发明提供被宽频带的可见光激发、能够发出高强度的近红外光的新的荧光体。提出了一种荧光体，其特征在于，包含式(1)：MCuSi2O6(式中的M包含Ba、Sr及Ca中的1种或2种以上)所示的晶相和式(2)：MCuSi4O10(式中的M包含Ba、Sr及Ca中的1种或2种以上)所示的晶相，并且，在通过使用了CuKα射线的粉末X射线衍射测定(XRD)得到的XRD图案中，MCuSi4O10的衍射峰强度相对于MCuSi2O6的衍射峰强度的比率β为0
摘要（英）：

The purpose of the present invention is to provide a novel fluorophore that is excited by a wide band of visible light, and that is capable of emitting near-infrared light of high intensity. Proposed is a fluorophore, characterized by having a crystal phase shown by formula (1): MCuSi2O6 (in the formula, M comprises one or more of Ba, Sr, and Ca), and a crystal phase shown by formula (2): MCuSi4O10 (in the formula, M comprises one or more of Ba, Sr, and Ca), the ratio Beta of the diffraction peak intensity of MCuSi4O10 to the diffraction peak intensity of MCuSi2O6 in an x-ray diffraction (XRD) pattern obtained by XRD measurement using CuK Alpha rays satisfying the relationship 0
