高发光的CsPbBr 3钙钛矿量子点（QD）在发电器件中的应用是非常有吸引力的。成功地制备了CsPbBr_3QD溶液及其相应的固体薄膜。通过透射电子显微镜、X射线衍射、紫外-可见分光光度法、光致发光和放射发光光谱等技术对所得量子点进行了表征。分析和讨论了CsPbBr 3QD薄膜作为能量转换材料在辐射发光核电池中的性能。比较了不同CsPbBr 3QD薄膜核电池的输出性能，探讨了其作为辐射发光层的可行性和优势。在此基础上，进行了长期等效使用行为研究，评价了CsPbBr 3辐射发光层的辐照稳定性，并预测了该类型核电池的使用寿命。利用物理模拟软件对氢离子在薄膜中的分布状态和渗透深度进行了分析和评价。光学和电学特性证实，这种钙钛矿材料可以为未来的能量转换和光电检测提供高效，稳定和可扩展的解决方案。
Highly luminescent CsPbBr3perovskite quantum dots (QDs) are very attractive for applications in power-generating devices. The CsPbBr3QD solution and its corresponding solid films were satisfactorily prepared. The obtained QDs were characterized by various techniques such as transmission electron microscopy, X-ray diffraction, ultraviolet–visible spectrophotometry, and photoluminescence and radioluminescence spectroscopy. The performance of the CsPbBr3QD films as an energy conversion material in radioluminescent nuclear batteries was analyzed and discussed. The output performance of different nuclear batteries based on CsPbBr3QD films was compared and the feasibility and advantages of using them as radioluminescent layers were investigated. On this basis, a long-term equivalent service behavior study was conducted to evaluate the irradiation stability of the CsPbBr3radioluminescent layer and predict the service life of this type of nuclear battery. The distribution state and penetration depth of hydrogen ions in the films were analyzed and evaluated using physics simulation software. Optical and electrical characteristics confirmed that this perovskite material could offer an efficient, stable, and scalable solution for energy conversion and photoelectric detection in the future.
