Abstract
An emitting phosphor is provided, which can be excited by a blue LED or a near-UV LED, emit visible light and increase internal quantum efficiency. An emitting phosphor is proposed, comprising an orthorhombic crystal system comprising Ga and S, wherein the orthorhombic crystal system has, in an XRD pattern using a Cu Kα beam, a proportion of the diffraction intensity of the maximum peak appearing at diffraction angle 2θ=16.0 to 18.0° with respect to the diffraction intensity of the maximum peak appearing at diffraction angle 2θ=23.6 to 24.8° of 0.4 or greater.
