GAGG(Ce) Scintillators

GAGG(Ce) gadolinium gallium aluminum garnet is a new detection material for high-end CT and security equipment. It has the advantages of high density, high light output, short decay time, and low radioactive background. Besides, it has stable chemical composition, no cleavability and no hygroscopy, and is easy to process and assemble, which can be applied in the fields of radiation detection and high energy physics.


OST Photonics can supply GAGG(Ce) crystals, GAGG(Ce) scintillation screens and LYSO(Ce) arrays upon your requests. We can offer a variety of design options and different types of GAGG(Ce) crystal materials to meet the needs of customers for their applications.

Scintillation Screen Design Options of GAGG(Ce) Scintillators (GAGG: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 or 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).
