LuAG(Ce) Scintillation Crystal
LuAG(Ce), or cerium-doped lutetium aluminum garnet, is a dense, non-hygroscopic garnet scintillator used in electron microscopy screens, X-ray imaging, and compact radiation detector systems. Typical reference values include a density of about 6.73 g/cm3, an emission peak near 535 nm, and a decay time around 70 ns. Its green emission can be matched with photodiodes, avalanche photodiodes, and suitable imaging sensors after the spectral response and optical coupling are reviewed. Final detector performance depends on crystal thickness, cerium concentration, surface finish, optical coupling, photosensor, and test conditions. ATR Crystal supplies custom LuAG(Ce) crystals and thin scintillation screens according to drawing and application requirements.

LuAG(Ce) Scintillator Crystals and Screens
LuAG(Ce) scintillator, also written as LuAG:Ce or Ce:LuAG, is cerium-doped lutetium aluminum garnet. It is a dense, non-hygroscopic crystal used in electron microscopy screens, X-ray imaging and radiation detector research.
ATR Crystal supplies custom LuAG(Ce) crystals and thin scintillation screens according to drawings and application requirements. Specify the active area, thickness, finished geometry, surface quality and optical readout when requesting a quotation.

Advantages of LuAG(Ce) Crystals and Screens
- Dense garnet hostUseful for detector components where the available active volume is limited.
- Non-hygroscopic materialMoisture handling can be reviewed together with the surface, mounting and packaging requirements.
- Screen and crystal formatsPolished crystals, thin screens and drawing-defined detector elements can be reviewed for the application.
- Mechanical and chemical stabilityThe garnet material is considered for precision scintillator components.
- Green emissionMatch the optical system or photosensor response to the scintillator emission.
- Imaging applicationsLuAG(Ce) is considered for electron microscopy and X-ray scintillation screens.
Screen Thickness, Optical Readout and Background
For a LuAG scintillation screen, provide the active area, thickness tolerance, mounting arrangement and intended camera or photosensor. Define the surface finish, light-collection face and any coating requirement on the drawing. The desired image response must be evaluated with the actual radiation energy and optical setup.
The listed decay time describes a material response. Define afterglow, exposure timing and image-uniformity requirements separately with the measurement conditions.
LuAG(Ce) contains lutetium and can contribute intrinsic background from naturally occurring Lu-176. A published LuAG:Ce, YAG:Ce and LYSO:Ce comparison discusses this background in lutetium-based scintillators. For low-count-rate work, provide the energy range, acquisition conditions and background acceptance criteria.

Frequently Asked Questions
What is LuAG(Ce) used for?
Can ATR Crystal review custom LuAG scintillation screens?
Is LuAG(Ce) hygroscopic?
Does LuAG(Ce) have intrinsic background?
What is needed for a LuAG(Ce) quotation?
How should active area and mounting area be defined for a LuAG(Ce) screen?
Show the full crystal outline, required active aperture and any rim or region reserved for mounting. Assign thickness and surface requirements to the relevant area, and identify the optical viewing face. The usable imaging area should not be assumed to equal the full external size when supports, edge margins or coatings cover part of the screen.
Does a specified LuAG(Ce) screen thickness guarantee image resolution?
No. Screen thickness is one component specification, while image resolution is a result of the complete imaging arrangement. Provide the optical magnification, readout pixel scale, radiation conditions and proposed resolution test if an imaging target matters. Keep that target separate from dimensional acceptance unless a system-level test has been explicitly agreed.
