In recent years, the development of new scintillation materials with red and near-infrared light emission has had significant advantages based on the development of an avalanche photodiode with high quantum yield. This study used a hydrothermal method to synthesize rare-earth-doped Cs2NaScCl6 crystals, in which a red emission of Cs2NaScCl6:Sm was investigated with high X-ray sensitivity and low detection limit. In addition, a tunable wavelength range of radioluminescence can be achieved, in which a near-white light emission can be generated by precisely controlling the proportion of Sm3+ and Tb3+ doping concentrations. Meanwhile, a Cs2NaScCl6:7%Sm scintillation film has been successfully prepared by direct coating with a thickness of 150 μm, which achieves a spatial resolution of 11.9 lp mm−1 based on X-ray imaging experiments. Therefore, this perovskite material has shown potential application as an eco-friendly multifunctional imaging material.

用于高分辨率 X 射线成像的发红光 Cs2NaScCl6:Sm 柔性薄膜

近年来,在高量子产率的雪崩光电二极管的开发基础上,开发红光和近红外光发射的新型闪烁材料具有显着的优势。本研究采用水热法合成稀土掺杂Cs 2 NaScCl 6晶体,并研究了Cs 2 NaScCl 6 :Sm的红光发射,具有高X射线灵敏度和低检测限。此外,还可以实现辐射发光波长范围的可调,其中通过精确控制Sm 3+和Tb 3+掺杂浓度的比例可以产生近白光发射。同时,通过直接涂覆成功制备了厚度为150 μm的Cs 2 NaScCl 6 :7%Sm闪烁薄膜,根据X射线成像实验,其空间分辨率达到11.9 lp mm -1 。因此,这种钙钛矿材料显示出作为环保型多功能成像材料的潜在应用前景。
