Abstract
Abstract In this work, we have investigated optical and scintillation properties of 0.35–0.65% Ce:(Gd 0.32 Y 0.68 ) 3 Al 5 O 12 (Ce:GYAG) transparent ceramics prepared by the vacuum sintering method. Obtained samples showed high transmittance in the spectral region longer than 500 nm, and two strong absorption bands were clearly observed below 380 nm and between 400 and 500 nm due to the 4f-5d transitions of Ce 3+ . Under UV and X-rays, we have also observed emission due to the 5d-4f transitions of Ce 3+ which appeared around 500–700 nm. The emission decay profile of PL consisted of a single exponential decay component with the decay time of 62.7–64.1 ns while the scintillation decay profile was approximated by a second-order exponential decay function with the decay times of 87.3–100 ns and 1.14–1.32 μs. In addition, it has been revealed that 0.65% Ce:GYAG transparent ceramic showed a notable light yield of 18,000 ph/MeV and low afterglow (13 ppm).
