Perovskites are extensively studied in scintillation detection due to their low cost, simple synthesis, high scintillation light yield, and rapid decay times. However, their instability to light and radiation leads to scintillation performance degradation. To address these stability concerns, this paper proposes a new perovskite nanocrystal (NC) synthesis method that employs aminopropyllsobutyl polyhedral oligomeric silsesquioxane (POSS) as a ligand and a coating layer to passivate the perovskite NCs, significantly enhancing their stability and photoluminescence efficiency. Furthermore, the resultant perovskite/aminopropyllsobutyl POSS nanocomposites exhibit remarkable capabilities in X-ray detection limits, imaging quality, and radiation hardness. These findings underscore the potential of enhanced perovskite in revolutionizing the field of scintillator materials, offering promising pathways for their future applications and development.
