Provided is a silicophosphate-based phosphor of Formula 1 and a light-emitting device including the same: <?in-line-formulae description="In-line Formulae" end="lead"?>[(Sr(1-x-y-a-b-c) BaaCabMgcEuxMny)4Si(PO4)4 (1)<?in-line-formulae description="In-line Formulae" end="tail"?> where 0<x<=0.2, 0<=y<=0.2, 0<=a<=0.2, 0<=b<=0.5, and 0<=c<=0.5. The silicophosphate-based phosphor of Formula 1 is chemically and thermally stable and can be easily prepared. The phosphor exhibits a high luminous property when excited by a UV LED excitation light source having a wavelength of 360-420 nm, and emits light having a wavelength of 570 to 630 nm. Accordingly, the silicophosphate-based phosphor can be used in a LED, a lamp, a self-emission type liquid crystal display device, or the like. In particular, when a white LED includes the silicophosphate-based phosphor, the color rendering index of the white LED is high and thus an excellent color rendering property can be obtained.
