Abstract

Cerium doped Barium Fluoride (BaF₂-Ce) transparent ceramic was fabricated and its luminescence and scintillation properties were studied. The photoluminescence shows the emission peaks at 310 nm and 323 nm and is related to the 5d-4f transitions in Ce³⁺ ion. Photo peak at 511 keV and 1274 keV were obtained with BaF₂-Ce transparent ceramic for Na-22 radioisotopes. Energy resolution of 13.5% at 662 keV is calculated for the BaF₂-Ce transparent ceramic. Light yield of 5100 photons/MeV was recorded for BaF₂-Ce(0.2%) ceramic and is comparable to its single crystal counterpart. Scintillation decay time measurements shows fast component of 58 ns and a relatively slow component of 434 ns under 662 keV gamma excitation. The slower component in BaF₂-Ce(0.2%) ceramic is about 200 ns faster than the STE emission in BaF₂ host and is associated with the dipole-dipole energy transfer from the host matrix to Ce³⁺ luminescence center.
