In recent years, the performance of metal halide perovskite (MHP)-based detectors (photon, biomedical, and X-ray detection) has significantly improved, resulting in higher carrier mobilities, longer carrier diffusion lengths, and excellent absorption coefficients. However, the widespread adoption of halide perovskites has been hindered by issues related to their stability and toxicity. Various strategies have been adopted to address these challenges, focusing on enhancing ambient stability and reducing toxicity by encapsulating MHPs within stable and robust host materials, such as silicon compounds, metal oxides, chalcogenides, and lead-free perovskites. This review focuses on recent developments in hybrid nanostructure-based detectors (photon, biomedical, and X-ray), particularly core/shell architectures, and provides a comprehensive analysis of techniques for mitigating degradation due to light and oxygen exposure, UV irradiance, and thermal effects. This review enhances the understanding of current advancements in core/shell-based detectors.
近年来，基于金属卤化物钙钛矿（MHP）的探测器（光子、生物医学和X射线探测）性能有了显著提升，具备了更高的载流子迁移率、更长的载流子扩散长度以及出色的吸收系数。然而，卤化物钙钛矿的广泛应用受到其稳定性和毒性相关问题的阻碍。人们采用了各种策略来应对这些挑战，重点是通过将MHP封装在稳定且坚固的主体材料（如硅化合物、金属氧化物、硫族化物和无铅钙钛矿）中来提高环境稳定性并降低毒性。本综述聚焦于基于混合纳米结构的探测器（光子、生物医学和X射线）的最新进展，特别是核壳结构，并对减轻因光和氧气暴露、紫外线辐照以及热效应导致的降解的技术进行了全面分析。本综述增进了对基于核壳结构探测器当前进展的理解。
