PROBLEM TO BE SOLVED : To provide an improved garnet material that is suitable for use of optoelectronic, e.g. a phosphor in an LED.
SOLUTION : A material is provided which comprises a garnet having the composition represented by the formula A3-xB5O12 : Dx and a barium-containing oxide. The content of barium in the material is 0.1 to 2.5 wt% and the material has a porosity of 0.001 to 2 vol % of the entire volume of the material. In the garnet A3-xB5O12 : Dx, A is lutetium, yttrium, gadolinium, terbium, scandium, or another rare earth metal or mixtures thereof, B is 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, and x is 0≤x≤2.
