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).
