Abstract

We have investigated scintillation and photoluminescence (PL) properties of Sr₂CeO₄ ceramics. The ceramic samples were synthesized by the solid state reaction method sintered at different temperatures (1100, 1200, 1300 and 1400 °C). All the Sr₂CeO₄ ceramic samples showed PL spectrum with a broad feature peaking around 460 nm. From decay constants of the PL emission, it was confirmed that the origin was due to the charge transfer (CT) transitions of O^2—Ce⁴⁺ ions. In addition, all the samples showed scintillation induced by X-rays with a spectrum peaking around 500 nm as similarly seen in PL. All of the samples exhibited a clear photoabsorption peak in the pulse height spectra measured under ¹³⁷Cs γ-ray irradiation, and the absolute scintillation light yield (LY) was the highest for the sample sintered at 1200 °C, and the value was 3200 ph/MeV.
