YAP(Ce) Scintillator (YAP(Ce) Scintillation Crystal)
Cerium-doped yttrium aluminum perovskite (YAP:Ce) is a high-performance inorganic scintillation crystal with a density of 5.4 g/cm³ and a fast decay time of ~28 ns. It offers a light yield of approximately 10,000–25,000 photons per MeV, with an emission peak at 370 nm that fits well with common photodetectors. YAP:Ce features high hardness, excellent radiation resistance and non-hygroscopicity, retaining stable performance in harsh environments. It is widely used in medium-energy gamma detection, industrial CT imaging and high-resolution radiation imaging applications.
OST Photonics offers high-quality cerium-doped yttrium aluminum perovskite (YAP:Ce) crystals and customized YAP:Ce scintillation screens, with a full range of tailored design options to meet the diverse application requirements of our customers.

Scintillation Screen Design Options of YAP(Ce) Scintillators
Freestanding ultra-thin scintillation screen.
Ultra-thin scintillation screens can be coupled to a substrate with optical adhesives in order to achieve better optical readout.
Scintillation screens can be inserted into frames(Aluminum, Stainless steel) for easier manipulation.
We can provide customized marking such as a grid, cross or scale on the surface of the screen for easier beam visualization.
We can provide various coating on the surface of the screen upon request, such as reflection coatings(Al, Au, Ag, etc.), AR coating, diffusion painting(TiO2, Al2O3), and conductive coatings(Al, ITO, C).
