Abstract
Multi-component rare-earth garnet optical materials comprising at least three different rare-earth elements and an optional activator ion are described. The optical materials include rare-earth garnet scintillators. Methods of preparing powders, ceramics, and single crystals of the optical materials are also described. In addition, radiation detectors comprising the rare-earth garnet scintillators are described.
