A printable ink mixture may include: a medium, orthophosphoric acid, at least one metal oxide, and at least one pigment. A method for producing a color print on a glass or ceramic surface may include: producing an ink mixture including a medium, orthophosphoric acid, at least one metal oxide, and at least one pigment, applying the ink mixture to the glass or ceramic surface, removing the medium from the ink mixture, and baking the ink mixture on the glass or ceramic surface to produce the color print.

A radiation-emitting component includes a semiconductor chip and a conversion element. The semiconductor chip includes an active layer suitable for generating electromagnetic radiation and a radiation exit face. The conversion element includes a matrix material and a luminescent material. The conversion element is arranged downstream of the radiation exit face of the semiconductor chip. The matrix material comprises at least 40 wt. % tellurium oxide and is free of boron trioxide and/or germanium oxide. A method for producing such a radiation-emitting component is furthermore stated.
