Abstract:
A semiconductor light-emitting device includes a semiconductor light-emitting element, and a sealing material sealing the semiconductor light-emitting element. The sealing material includes a phosphor which includes a matrix including a glass and a luminescence center included in the matrix. A refractive index of the matrix is more in a far side of the matrix than the refractive index of the matrix in a near side of the matrix, the far side being located farther from the semiconductor light-emitting element than the near side. The refractive index of the matrix is the same as a refractive index of the semiconductor light-emitting element.
