In this study, high concentration (5 mol%) of cerium doped barium fluoride transparent ceramic was fabricated by hot pressing method t a temperature of 1200 °C under 30 MPa. XRD (X-ray Diffraction), SEM (Scanning Electron Microscope), PLE (Photoluminescence Emission) measurements was used to investigate the phase composition, microstructure as well as photoluminescence properties of Ce${}^{3+}$: BaF₂. XEL (X-ray Excited Luminescence) and pulse height spectrum were used to investigate the scintillation properties of this ceramic. The phase composition and microstructure analyses showed that the Ce${}^{3+}$: BaF₂precursor nanoparticles prepared by the co-precipitation method were uniform and have a average size of 25 nm. The highest transmittance of the ceramic was 77% at the wavelength of 2300 nm. The PL (photoluminescence) spectrum showed that the 5d–4f transition of Ce${}^{3+}$: BaF₂ transparent ceramic is located at 340 nm. X-ray excited luminescence exhibited only one violet peak at 392 nm. Scintillation decay time measurements showed only a slow component of 437 ns under 662 keV gamma excitation.

在这项研究中，通过热压法在1200℃的温度和30 MPa的压力下制备了高浓度（5 mol％）的掺铈的氟化钡透明陶瓷。XRD（X射线衍射），SEM（扫描电子显微镜），PLE（光致发光发射）测量用于研究铈的相组成，微观结构以及光致发光性能${}^{3+}$：BaF ₂。使用XEL（X射线激发发光）和脉冲高度谱研究了这种陶瓷的闪烁特性。相组成和微观结构分析表明，铈${}^{3+}$通过共沉淀法制备的BaF ₂前体纳米颗粒是均匀的，并且平均尺寸为25nm。陶瓷的最高透射率在2300 nm波长下为77％。PL（光致发光）光谱显示Ce的5d–4f跃迁${}^{3+}$：BaF ₂透明陶瓷位于340 nm。X射线激发的发光在392nm处仅显示一个紫峰。闪烁衰减时间测量结果显示，在662 keVγ激发下，只有437 ns的慢分量。
