Precision YSO(Ce) Scintillators: Zero Background & Fast Decay
Cerium-doped Yttrium Orthosilicate (YSO:Ce) is a premier rare-earth scintillator engineered for the world’s most sensitive detection fields. Crucially, unlike LYSO, YSO(Ce) contains no Lutetium, delivering an absolute zero-background performance that is mandatory for ultra-precise, low-level radiation monitoring.
Highly radiation-resistant and strictly non-deliquescent (non-hygroscopic), this rugged crystal boasts a high density of 4.45g/cm³ and a rapid decay time of 50-70ns. Emitting at a peak wavelength of 420nm, it ensures seamless and highly efficient coupling with standard photodetectors.
ATR Crystal custom-manufactures standalone YSO(Ce) crystals, ultra-thin scintillation screens, and precision YSO(Ce) arrays. By optimizing every design with premium reflector materials, we guarantee high light output, exceptional pixel-to-pixel uniformity, and minimal optical crosstalk for demanding applications across PET imaging, nuclear physics, and industrial NDT.

Scintillation Screen Design Options of YSO(Ce) Scintillators (YSO: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, 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 of 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).
