采用放电等离子体烧结法制备了BaBr_2：Eu（0.5mol%）半透明陶瓷，并对其光学、闪烁和光致发光（OSL）性能进行了研究。为了评估半透明陶瓷的潜力，BaBr 2：Eu（0.5mol%）单晶已通过垂直Bridgman-Stockbarger方法生长用于比较。当晶体和陶瓷样品的厚度固定为约0.5mm时，两个样品在可见光范围内均显示半透明性。在闪烁光谱中，两种样品均在400和500 nm附近出现两个发射峰，发射源分别为Eu 2+的5d-4f跃迁和F-VK心复合。关于X射线照射后的OSL性质，样品的OSL光谱显示峰值在400 nm附近的发射带，晶体和陶瓷样品的检测限分别为1和10 mGy。
BaBr2:Eu (0.5 mol%) translucent ceramic has been synthesized using spark plasma sintering, and then the optical, scintillation and optically-stimulated luminescence (OSL) properties have been investigated. To evaluate the potential of translucent ceramics, BaBr2:Eu (0.5 mol%) single crystal has been grown by the vertical Bridgman–Stockbarger method for the comparison. When the thickness of the crystal and ceramic samples were fixed to approximately 0.5 mm, both the samples showed translucency in the visible light range. In the scintillation spectra, both the samples showed two emission peaks at around 400 and 500 nm, and the origin of the emissions were the 5d–4f transitions of Eu2+and the F-VKcenter recombination, respectively. Regarding the OSL properties after x-ray irradiation, the OSL spectra of the samples showed an emission band peaking at around 400 nm, and the detection limit of the crystal and ceramic samples were 1 and 10 mGy, respectively.
