辐射发光核电池是一种可小型化的能量转换装置，具有将核能转化为光能，再转化为电能的能力。为了探究荧光粉层结构与辐射发光核电池电性能之间的响应关系，利用蒙特卡罗方法建立了物理模型来研究沉积能量分布。利用放射发光光谱和电流-电压特性曲线来研究光学和电学性质。通过对单平面层、双平面层、V槽层结构的综合比较，模拟结果与实验结果一致。结果表明，蒙特卡罗模拟适用于辐射发光核电池荧光粉层结构的分析。此外，结果还表明荧光粉层的结构类型和物理参数对能量沉积有很大影响。合适的荧光粉层结构可以为展现更高的能量转换效率以及提高放射性粒子射程与荧光粉层厚度之间的匹配度提供新途径。
Radioluminescent nuclear battery is a type of energy conversion device that can be miniaturized, which has the ability to convert nuclear energy into light energy, and again into electrical energy. To explore the response relationship between the phosphor layer structure and the electrical performance of radioluminescent nuclear battery, the physical model was established to research the deposition energy distribution by using Monte Carlo method. The radioluminescence spectra and current‐voltage characteristic curves were used to investigate the optical and electrical properties. Through a comprehensive comparison of single plane layer, double plane layer, and V groove layer structures, the simulated results are consistent with experimental results. The results indicate that the Monte Carlo simulation is applicable to analysis of the phosphor layer structure of radioluminescent nuclear battery. Additionally, the results also show that the structure type and physical parameters of the phosphor layer have great influence on the energy deposition. A suitable phosphor layer structure can provide a new route to exhibit higher energy conversion efficiency as well as improving the matching degree between the range of radioactive particles and the thickness of the phosphor layer.
