GAGG(Ce) Scintillation Crystal for Gamma and X-Ray Detection
GAGG(Ce) scintillation crystal, also written as GAGG:Ce or Ce-doped gadolinium aluminum gallium garnet, is a dense, non-hygroscopic oxide scintillator used for gamma-ray detection, X-ray imaging, PET/SPECT research, security inspection, high-energy physics instrumentation, and compact detector modules.
The material is often selected when a project needs high light output, practical handling, green emission around 520 nm, and compatibility with modern photosensors such as SiPMs and photodiodes. Compared with LYSO(Ce), GAGG(Ce) does not contain Lu-176 intrinsic background, which can be useful for low-background detector designs.
ATR Crystal supplies GAGG(Ce) crystals, ultra-thin scintillation screens, monolithic components, and pixelated arrays according to drawings or application requirements. Size, polishing, coating, reflector, substrate coupling, frame design, and readout matching can be reviewed before quotation.
Advantages of GAGG(Ce) Scintillation Crystal
- High light outputDifferent GAGG(Ce) grades can provide strong signal output for gamma and X-ray detector designs.
- Non-hygroscopic handlingGAGG(Ce) is easier to handle than hygroscopic materials such as NaI(Tl), LaBr3(Ce), and CeBr3.
- 520 nm green emissionThe emission peak is suitable for many SiPM, photodiode, and modern optical readout systems.
- No Lu-176 intrinsic backgroundUnlike LYSO(Ce), GAGG(Ce) does not contain lutetium-based intrinsic radioactivity.
- Grade selectionHigh light output, low afterglow, fast decay, and balanced types can be reviewed according to the detector priority.
- Custom formatsMonolithic crystals, scintillation screens, substrate-coupled screens, frames, coatings, and pixelated arrays can be discussed.

GAGG Crystal Price and Custom Quotation
GAGG crystal price depends on the material grade, finished dimensions, surface treatment and quantity. A monolithic crystal, a thin scintillation screen and a pixelated array require different processing and quotation details.
To compare quotations for the same component, define these requirements:
- Grade and performance: high light output, low afterglow, fast decay or balanced type, together with the acceptance criteria.
- Geometry: finished dimensions and tolerances; for arrays, include pixel size, pitch and layout.
- Optical finish: polished faces, coupling face, coatings and reflector or wrapping requirements.
- Screen or array construction: specify any substrate, frame, reflector or bonding requirement.
- Quantity: state the number of pieces or arrays required.
For a custom GAGG(Ce) crystal quotation, send your drawing or dimensions, quantity and intended application. Include the target energy range and PMT, SiPM, photodiode or camera readout where known. The table below lists the information needed for engineering review.

Frequently Asked Questions
What is GAGG(Ce) scintillation crystal used for?
Is GAGG(Ce) hygroscopic?
Does GAGG(Ce) have intrinsic background?
Which GAGG(Ce) grade should I choose?
Confirm light yield, decay time and afterglow together for the selected grade. The highest light yield and fastest decay values in different grade rows should not be combined into one specification without confirmation.
Can GAGG(Ce) be made into a pixelated array?
What should accompany a quoted GAGG energy-resolution value?
Ask for the crystal dimensions, radiation energy, photosensor, optical coupling and measurement conditions associated with the value. Keep the reference value on the material page separate from the acceptance limit for your component. A quotation should identify the agreed configuration and test basis before an energy-resolution requirement is treated as a delivery criterion.
