Hybrid organic-inorganic materials incorporating high- nanocompounds represent an emerging area of research with high, cost-effective potential for radiation detection applications, owing to their ability to enable unprecedented architectures and functional devices. Herein, we introduce a new hybrid system composed of tungstate nanoparticles (SrWO or CdWO) blended with P3HT:PCBM, engineered for direct X-ray detection without the need for external bias. The nanocrystalline tungstates were synthesized through a hydrothermal route. X-ray diffraction and scanning electron microscopy were employed to characterize the nanoparticle structure and morphology, respectively. Incorporation of high- tungstate nanoparticles was found to substantially enhance detector sensitivity within specific energy ranges, with performance tunable by varying the tungstate composition. The use of the fabricated detectors was demonstrated for both spectroscopic and imaging applications.
包含高纳米化合物的有机-无机杂化材料代表了一个新兴的研究领域，由于其能够实现前所未有的结构和功能器件，在辐射探测应用方面具有高性价比的潜力。在此，我们介绍一种由钨酸盐纳米颗粒（SrWO₄或CdWO₄）与P3HT:PCBM混合而成的新型杂化系统，该系统经过设计可用于直接X射线探测，无需外部偏压。通过水热法合成了纳米晶钨酸盐。分别采用X射线衍射和扫描电子显微镜对纳米颗粒的结构和形态进行了表征。发现在特定能量范围内，掺入高钨酸盐纳米颗粒可大幅提高探测器灵敏度，其性能可通过改变钨酸盐组成进行调节。所制备的探测器在光谱和成像应用中均得到了验证。
