PAM XIAMEN offers Sodium-bismuth tungstate (NaBi(WO4)2.
Sodium-bismuth tungstate (NaBi(WO4)2 or NBWO) is a scintillator material possessing very high optical quality, high density and radiation hardness. Due to these properties NBWO crystals are widely used in quantum electronics, acousto-optics and high-energy physics, in particular, in Cherenkov detecting and solid state Raman laser shiftin
NaBi(WO4)2 is grown from the melt by Czochralski method. If specific qualities are required NBWO can be doped with In or other elements
