GAGG(Ce) is new scintillator for single photon emission computed tomography(SPECT), gamma-ray and compton electron detection. Cerium doped GAGG have many properties that make it suitable for gamma spectroscopy and medical imaging applications.
(La,Sr)(Al,Ta)O3 is a relatively mature non-luan crystal perovskite crystal, which is well matched with high-temperature superconductors and various oxide materials.
The lattice mismatch rate between lithium aluminate single crystal and gallium nitride is very small (1.4% for lithium aluminate), making it a high-quality substrate for gallium nitride thin films.
