Abstract
Electric sintering of precursor materials to prepare phosphor ceramics is described herein. The phosphor ceramics prepared by electric sintering may be incorporated into devices such as light-emitting devices, lasers, or used for other purposes.
Claims20
A method of preparing a dense phosphor ceramic, comprising:
- heating a multi-elemental composition to sinter the composition by applying a pulse electric current to the composition at a pressure of about 1 MPa to about 500 MPa, wherein the multi-elemental composition comprises:
- a garnet or a garnet precursor;
- and
- a nitride or a nitride precursor;
- wherein the method produces a dense phosphor ceramic.
2 more elements
A ceramic compact comprising a first layer comprising garnet material and a second layer comprising a nitride material.
