Product Overview

Description

 

high quality X-ray imaging Cerium-doped Lutetium Yttrium Orthosilicate

LYSO:Ce ( (Lu,Y)₂SiO₅:CeLutetium-Yttrium OxyorthoSilicate, Ce⁺³ doped, Cerium-doped Lutetium Yttrium Orthosilicate) scintillator crystal is a new type of scintillation materials, it has the excellent scintillation properties, like high light output, short decay time, high density and anti-radiation hardness, and with stable chemical and physical properties. These properties make LYSO an ideal candidate for a range of ray detection applications in nuclear physics and nuclear medicine, which require higher, improved timing resolution and superior energy revolution. 

 1. High-density

 2. Good mechnical stability and chemical stability

 3. Suitable emission wavelength for PMTs
