采用放电等离子烧结法制备了Eu：BaFBr半透明陶瓷，并对其晶体结构、光学和光致发光性能进行了研究。合成的0.05- 0.5%Eu：BaFBr半透明，透光率为30- 50%。由于Eu ~（2+）离子的存在，样品的光致发光和光致发光光谱均由峰值在390 nm左右的发射带组成。当掺杂浓度为0.5%时，PSL的光致发光量子产率和对X射线的灵敏度最高，均高于市售Eu：BaFBr成像板（IP）。此外，通过使用0.5%Eu：BaFBr半透明陶瓷作为成像板获得的X射线图像的空间分辨率高于通过使用商业IP获得的空间分辨率。
Eu:BaFBr translucent ceramics were synthesized by the spark plasma sintering method, and then the crystal structure, optical and photostimulated luminescence (PSL) properties were investigated. The synthesized 0.05–0.5% Eu:BaFBr are translucent, and the optical transmittance is 30–50%. The photoluminescence and PSL spectra consist of an emission band peaking around 390 nm due to the presence of Eu2+ion. The photoluminescence quantum yield and the sensitivity of PSL to X-rays are the highest when the doping concentration is 0.5%, and they are higher than those of the commercial Eu:BaFBr imaging plate (IP). In addition, the spatial resolution of an X-ray image obtained by using the 0.5% Eu:BaFBr translucent ceramic as an imaging plate is higher than the one obtained by using the commercial IP.
