Abstract
Provided is a new phosphor which can be excited by visible light in a wide band to emit a broad fluorescence spectrum, and also to emit near-infrared light with high intensity. Proposed is a phosphor, which is an oxide comprising Ca, Cu, and Si, wherein the containing molar ratios of the elements are 0.15≤Ca/Si<0.25 and 0.13≤Cu/Si<0.25.
