A method for preparing a glass composite wavelength converter comprising the steps of providing at least one phosphor material, providing a powder of glass components, mixing the phosphor material and the powder of glass components, thereby preparing a first mixture, adding at least one oxidizing agent to the first mixture, mixing the oxidizing agent with the first mixture, thereby preparing a second mixture, applying pressure and current to the second mixture, thereby preparing a glass composite wavelength converter is described. Furthermore, a glass component wavelength converter and a light source are described.
