More particularly, the scintillators include lutetium ***---- yttrium aluminum garnet (LuYAG)-type materials that are doped with an activator, such as praseodymium, and codoped with a mono- valent cation, such as lithium. Radiation detectors comprising the scintillators, methods of detecting higher energy radiation using the O scintillators, and methods of preparing the scintillators and altering scintillator properties are also described.
