Claim 0:
1. A phosphor with garnet structure, wherein the phosphor comprises the following components in percentage by weight: 38.47-45.19% of Y element, 9.49-22.09% of Al element, 2.06-24.31% of Ga element, 27.3-32.04% of O element and 0.43-1.46% of Ce element; the shortest distance from the surface of one side of the phosphor to the surface of the opposite side through the centroid of the phosphor is defined as R, 5 μm≤R≤40 μm;
any distance from the phosphor surface to the centroid is r, 0<r<½R; and the space with the distance from the phosphor surface to the centroid direction being less than or equal to r is defined as rinner, and the space with the distance from the phosphor surface to the centroid direction being greater than r is defined as router, whereat the ratio of the weight percentage of Ga elements in any unit volume in router to rinner is n, and 0≤n≤1.
