Luminescence of Ce3+ in some chloroaluminates

Scintillation and Dosimetric Properties of Ce:CsCl Transparent Ceramics

“…Ce:CsCl is known to show emission peaks at around 250, 360, and 380 nm, which are due to Augerfree luminescence (AFL) and 5d→4f ( 2 F 5/2 and 2 F 7/2 ) transitions of Ce 3+ , (14) respectively. The decay time constants of the AFL at 8 K and the 5d-4f transitions of Ce 3+ at room temperature are known to be ~2 and ~20 ns, (14,15) respectively. Up to now, some scintillation properties of Ce:CsCl have been reported in the literature; however, most studies were carried out on bulk single crystals, and no reports can be found for transparent ceramics.…”

Synthesis of KMgCl3 nanomaterial and luminescence of Ce3+/Dy3+/Eu3+ by different routes

“…The subsequent de-excitation occurs by an allowed 5d-4f electric dipole transition with a decay time of the order of few ns 3-50 ns. In LaF 3 :Ce 3 þ the fast decay time is experimentally determined to be 20 ns [37] and that in LiCAF:Ce 3 þ 25 ns [38][39][40][41][42].…”

Synthesis and characterization of KCe(PO3)4 doped with some lanthanide activators

“…Amongst rare‐earth ions, Ce 3+ exhibits rather peculiar emission which is in the form of two humped broad bands, due to split ground state . Cerium (Ce 3+ ) ion exhibits intense emission due to allowed electric dipole transitions corresponding to transitions from levels of 5d 1 configuration to 2 F j states of 4f 1 configuration with fast decay time of the order of several nanoseconds. Quenching usually occurs at high concentrations barring some exceptions like YAG:Ce.…”
