Harnessing Self-Sensitized Scintillation by Supramolecular Engineering of CsPbBr₃ Nanocrystals in Dense Mesoporous Template Nanospheres.

ABSTRACT: Perovskite-based nanoscintillators, such as CsPbBr₃ nanocrystals (NCs), are emerging as promising candidates for ionizing radiation detection, thanks to their high emission efficiency, rapid response, and facile synthesis. However, their nanoscale dimensions - smaller than the mean free path of secondary carriers - and relatively low emitter density per unit volume, limited by their high molecular weight and reabsorption losses, restrict efficient secondary carrier conversion and hamper their practical deployment. In this work, a strategy is introduced to enhance scintillation performance by organizing NCs into densely packed domains within porous SiO₂ mesospheres (MSNs). This engineered architecture achieves up to a 40-fold increase in radioluminescence intensity com
