Yttrium silicate crystal (YSO) has no spontaneous emission and can be used in a wide range of applications

Yttrium silicate, chemical formula Y2SiO5, appears as white powder, insoluble in water and difficult to dissolve in acid. It can be used as a heat insulation, corrosion-resistant, anti-oxidation coating material, as well as scintillation crystal, fluorescent material, and luminescent material. Yttrium silicate crystal, referred to as YSO, is grown using the Czochralski method. It is…
