Cerium doped yttrium aluminum (or Ce:YAP) crystals is a type of fast scintillating materials, it is mechanically strong and chemically inert, suitable for precise mechanical fabrications. A very thin aluminum layer film could be deposited on the entrance surface to avoid the light-sensitivity. YAP(Ce) can well suit for imagining applications due to its ultra-low energy secondary X-ray emissions. Ce:YAP detectors are widely used in the field of gamma and X-ray counting, electron microscopy, electron and X-ray imaging screens, and computer tomography systems.
