Some phosphor powders can be difficult to form into ceramic compacts because they are difficult to sinter. As described herein, phosphor powders that can degrade under conventional sintering temperatures can be sintered by heating the powder at a lower temperature, such as less than 800&#xb0; C., while the powder is under greater than atmospheric pressure, such as at least 0.05 GPa. Phosphor ceramic compacts prepared by this method, and light-emitting devices incorporating these phosphor ceramic compacts, are also described.
