Effects of Ce3+ doping concentrations on microstructure and luminescent properties of Ce3+:Lu3Al5O12 (Ce:LuAG) transparent ceramics

Optical and Scintillation Properties of Ce3+‐Doped LuAG and YAG Transparent Ceramics: A Comparative Study

“…Scintillation decay time of LuAG:Ce transparent ceramic exhibits a biexponential decay with fast component of 59 ns and intensity of 61.5% followed by a slower component, with a 620 ns decay time and intensity of 38.5%. The fast decay component of 59 ns is in agreement with the typical value of about 50–80 ns, reported by various authors . In contrast, YAG:Ce transparent ceramic exhibits only a fast decay time of 76 ns.…”

“…The value of energy resolutions obtained is relatively high compared to the reports on energy resolution of Ce 3+doped LuAG and YAG ceramics. To the best of our knowledge, the best value of energy resolution at 662 keV reported for LuAG:Ce transparent ceramic is 12% for relatively thin sample of 0.02 at.% Ce-doped LuAG transparent ceramic, 44 whereas 7.2% for 0.5% Ce 3+ -doped YAG transparent ceramic of dimension Ø 44,45 In contrast, YAG:Ce transparent ceramic exhibits only a fast decay time of 76 ns. Table 2 presents the scintillation properties of cerium-activated LuAG and YAG transparent ceramic.…”

A Comparison on Ce3+ Luminescence in Borate Glass and YAG Ceramic: Understanding the Role of Host’s Characteristics

“…Another issue is the Ce 3+ −Ce 4+ electron transfer interaction, which is energetically favorable 56 but still does not incorporate any significant quenching, may be due to the preferential segregation of Ce 4+ cations. 66 The 10−15% QY loss observed in studied YAG:Ce may be related to the electron transfer interactions.…”

Multicenters in Ce3+ visible emission of YAG ceramics

“…Al antisites is smaller, other defects due to microstructure characteristics could appear [22,23]. The recorded absorption, emission under different excitation wavelengths in visible and emission kinetics under pulsed laser with 532 nm of Ce:YAG transparent ceramics, at different temperatures (10-300 K) are analyzed and a comparison with recent results on Ce:YAG is presented.…”
