LuAG(Pr) Scintillation Crystal
ATR Crystal reviews custom LuAG(Pr) scintillation crystals for detector development. Provide crystal dimensions, surface finish, photosensor model and acceptance requirements. Existing material reference values require confirmation for the quoted configuration; detector timing and elevated-temperature performance depend on the complete design and test conditions.
Built around your specification
- Crystal dimensions
- Cross-section, length and tolerances per drawing
- Surface finish
- Identify polished faces and other required finishes
- Readout face
- Mark the optical coupling face on the drawing
- Acceptance testing
- Agree measurement conditions and acceptance limits
Final specifications and acceptance criteria are confirmed for the quoted configuration.

LuAG(Pr) Scintillation Crystal for Detector Development
LuAG(Pr), also written LuAG:Pr, is praseodymium-doped lutetium aluminum garnet. Its near-ultraviolet scintillation emission and fast response make photosensor selection a central part of the detector design. ATR Crystal reviews custom crystal geometry, optical surfaces and inspection requirements against your drawing.
Specify the active crystal size and coupling arrangement together with the radiation source and measurement objective. For other garnet options, review LuAG(Ce) or the scintillation crystal range.
Photosensor Matching and Light Collection
Check the photosensor response near 310 nm, including the transmission of its entrance window and any coupling material or coating in the light path. A sensor with strong visible-light response may need a separate ultraviolet-response review.
Define the coupling face, surface finish and reflector arrangement together with the sensor active area. If light yield or energy resolution is required, specify the irradiation energy, crystal size, optical coupling, photosensor and integration or shaping settings. Agree the calculation method and reporting format before ordering.
Inspection and Acceptance
Separate dimensional and visual inspection from scintillation performance measurements. Define permitted surface defects and tolerances on the drawing. Ask which tests and reports are included in the quotation, and agree the measurement conditions and limits before production.

LuAG(Pr) Material Properties and Reference Conditions
These values are starting points for material selection, not inspection results for the quoted crystals. Confirm the material grade and measurement conditions before setting purchase acceptance limits.
| Property | Reference value | Use in specification review |
|---|---|---|
| Density | 6.73 g/cm3 | Existing ATR material reference; confirm the quoted grade |
| Peak emission | Near 310 nm | Review sensor response and optical-path transmission |
| Decay time | About 22 ns | Material reference; not detector coincidence timing resolution |
| Light yield | 22,000–23,000 photons/MeV | Existing ATR reference; confirm source, integration method and optical collection |
| Hygroscopicity | Non-hygroscopic | Protect optical surfaces and define assembly handling requirements |
| Hardness | 8 Mohs | Material reference; does not establish a minimum machinable size |
A published LuAG(Ce/Pr) manufacturer comparison lists LuAG(Pr) emission at 310 nm and decay at 22 ns. Its light-output value differs from the reference above; supplier tables must not be treated as interchangeable batch certificates.
A study of LuAG:Pr luminescence and scintillation reports near-310 nm emission and about-20 ns photoluminescence decay for the investigated samples. Photoluminescence decay, scintillation response and detector timing describe different measurements. Define the required test rather than substituting one value for another.
Applications
Applications and Detector Evaluation
- Fast scintillation detector research
- Electron and X-ray detection development
- High-energy physics detector studies
- Medical imaging detector research with a defined readout evaluation
For timing-sensitive applications, evaluate the crystal, photosensor and electronics as a complete measurement chain. A 22 ns material decay reference alone does not establish coincidence timing resolution or suitability for a specified TOF-PET system.
For elevated-temperature operation, provide the temperature range, exposure duration, thermal cycling and required response stability. Review the crystal, coupling materials, housing and photosensor together; material selection alone does not guarantee continuous detector performance at high temperature.

Frequently Asked Questions
Does 22 ns establish detector TOF resolution?
What matters for LuAG(Pr) photosensor selection?
Identify every window, coating and coupling layer between the crystal and sensor. Request transmission information at the relevant emission band and specify the actual layer thickness where applicable. A sensor response curve alone does not describe the transmission of the assembled optical path.
Is a fixed energy-resolution value guaranteed?
How should high-temperature use be specified?
What should be included when replacing LuAG(Ce) with LuAG(Pr)?
State the activator explicitly in the part specification and review the photosensor, optical-path transmission and signal integration settings for the proposed material. Retaining the same external crystal dimensions does not establish readout equivalence. Ask for the relevant material properties and acceptance conditions for the Pr-activated component rather than reusing the Ce-activated specification unchanged.
