| description | New scintillation transparent ceramics Y<sub>3</sub>Al<sub>2.5</sub>Ga<sub>2.5</sub>O<sub>12</sub>:Ce, Mg has been produced and evaluated for the first time. The material possesses a density of 5.17 g/cm<sup>3</sup>, a highlight yield of 44,000 ph/MeV, and an effective scintillation kinetics decay constant of 47 ns. This unique combination of the parameters makes it superior to YAG:Ce. Production of the material does not include tooling from precious materials, and the rate of the crystalline mass production is not limited by the pulling rate of the crystal growth process. It can be quite prospective to upgrade the detection units of a variety of X-ray imaging devices. The mechanism of the scintillation light yield enhancement and kinetics shortening in the material are discussed as well. |
