YAG(Ce) Scintillator (YAG(Ce) Scintillation Crystal)
Cerium-doped yttrium aluminum garnet (YAG:Ce) is a high-performance inorganic scintillation crystal with excellent physical and scintillation properties. It features a fast decay time of ~70 ns, high light yield of ~18,000 photons per MeV, and a prominent emission peak at 550 nm that matches well with silicon photodiodes. Boasting outstanding radiation hardness, good thermal stability and non-hygroscopicity, it can work stably in harsh extreme environments. It is widely applied in radiotherapy dose distribution detection, high-resolution X-ray imaging and high-energy particle monitoring.
OST Photonics can supply high-quality YAG:Ce crystals and customized YAG:Ce scintillation screens, with a full range of design options tailored to meet the diverse application requirements of our customers.

Scintillation Screen Design Options of YAG(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 markings 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).
