YSO(Ce) Scintillation Crystal
YSO(Ce), or cerium-doped yttrium orthosilicate, is a non-hygroscopic scintillation crystal used in X-ray and gamma detection, charged-particle measurement, nuclear physics experiments, and detector research. Because it contains no lutetium, YSO(Ce) does not have the Lu-176 intrinsic activity associated with LYSO(Ce), although total detector background still depends on material purity, packaging, photosensor, electronics, and the operating environment. Typical reference values include a density of about 4.45 g/cm3, an emission peak near 420 nm, and a decay time of approximately 50-70 ns. ATR Crystal supplies custom YSO(Ce) crystals, screens, and array components with dimensions, surface finish, reflector, and readout requirements reviewed according to the detector design.

YSO(Ce) Lutetium-Free Scintillation Crystal
YSO(Ce) scintillation crystal, also written as YSO:Ce, is cerium-doped yttrium orthosilicate (Y2SiO5:Ce). This non-hygroscopic, lutetium-free material is considered for radiation detection, imaging research and low-background detector studies.
ATR Crystal supplies YSO(Ce) Scintillation Crystal for research, industrial, medical, security, and OEM projects. Dimensions, surface finish, packaging, readout matching, and inspection requirements can be reviewed according to your drawing or application.
Because the YSO host contains no lutetium, it avoids the Lu-176 contribution associated with lutetium-based scintillators. This does not mean that a finished detector has zero background. Material purity, surrounding components, photosensor, electronics and environment still need review for the intended measurement.

YSO(Ce) vs. LYSO(Ce) and GAGG(Ce)
Compare host composition, component geometry, optical readout and the required measurement background. The following review points support material selection; they do not specify guaranteed detector performance.
| Material | Selection distinction | Review for the project |
|---|---|---|
| YSO(Ce) | Lutetium-free silicate scintillator without the Lu-176 contribution of a lutetium-based host. | Required radiation range, thickness, light collection and measured background. |
| LYSO(Ce) | Lutetium-containing silicate used for compact gamma detection and PET research. | Intrinsic Lu-176 background, geometry and photosensor response in the intended energy window. |
| GAGG(Ce) | Lutetium-free, green-emitting garnet scintillator. | Emission/readout matching, material grade, afterglow conditions and required format. |
A published study of intrinsic radioactivity in LYSO describes the Lu-176 contribution. For low-count-rate work, provide the energy window, acquisition conditions and background acceptance criteria.

Frequently Asked Questions
What information is needed for a YSO(Ce) Scintillation Crystal quotation?
Can ATR Crystal customize YSO(Ce) Scintillation Crystal?
What applications is YSO(Ce) Scintillation Crystal used for?
Does lutetium-free YSO(Ce) mean zero detector background?
Define the energy interval, crystal dimensions, acquisition time and background limit, and identify the surrounding components included in the measurement. State whether the result is required for the crystal or an assembled readout. Avoid using the absence of lutetium as a substitute for an agreed background measurement under the intended conditions.
Can samples and production quantities both be supplied?
Can an existing LYSO drawing be used unchanged to order YSO(Ce)?
It can serve as a starting point for geometry, but update the material designation and review the scintillation, optical-readout and acceptance requirements. Identify which dimensions must remain fixed and which performance targets need reassessment. The similar material abbreviations should not be taken to mean that a YSO component will reproduce the response of a LYSO component.
