A radiation-emitting component comprising a ceramic material, comprising a garnet having the composition represented by the formula A3-xB5O12 : Dx and a barium-containing oxide. In the garnet A3-xB5O12 : Dx, A is selected from lutetium, yttrium, gadolinium, terbium, scandium, another rare earth metal or mixtures thereof. B is selected from aluminum, scandium, gallium, indium, boron or mixtures thereof. D is at least one dopant selected from chromium, manganese and rare earth metals, particularly cerium, praseodymium or gadolinium. The dopant is present with x is 0≤x≤2.
