LBC (Lanthanum BromoChloride) LaBr₂.₈₅Cl₀.₁₅:Ce

LBC (Lanthanum BromoChloride) LaBr₂.₈₅Cl₀.₁₅:Ce scintillators have similar properties to the well-known LaBr₃:Ce crystals. Energy resolutions around 3 % FWHM (662 keV) are standard and the material is mechanically a little stronger than LaBr₃. In contrast to background free LaBr₃, LBC crystals suffer from the same La-138 background as LaBr₃

  • Material – LBC
  • Density (g/cm3) – 4.90
