| 520 | _ | _ | |a In recent years, perovskite nanocrystals (CsPbX3, with X = Cl, Br, I) have emerged as a new class of materials for photonic and optoelectronic applications due to their exceptional synthetic scalability through solution-based processes, room-temperature fabrication and remarkable physical properties such as high emission efficiency and defect tolerance. Additionally, these materials possess tunable optical properties through controlled adjustments of their size and composition. Over the course of my three-year research project, I focused on the use of perovskite nanocrystals for scintillation applications, with particular emphasis on the synthesis and characterization of polymer-based perovskite nanocomposites. These nanomaterials were found to exhibit two characteristics of considerable interest for scintillation: high radiation resistance (up to 1 MGy without compromising optical properties) and rapid scintillation, with decay times around 200 ps for CsPbCl3 and 1.1 ns for CsPbBr3. The articles published within the scope of my thesis work include, in addition to studies on synthesis and characterization, theoretical models explaining the scintillation of these nanostructures and the ultra-fast characteristics of their scintillation emission, attributed to multi-exciton generation within the material. During a research period at BCMaterials (Bilbao, Spain), I also gained expertise in computational chemistry, which proved useful for performing delicate polymer encapsulation of the nanostructures. Specifically, I conducted DFT calculations to analyze defects within the nanocrystals and molecular dynamics simulations to study ligand shell behavior on these structures. Importantly, some of the nanocomposites produced were tested in high-energy physics experiments at CERN (Geneva, Switzerland), where radiation hardness and ultra-fast scintillation are essential requirements. Finally, the application of these materials was explored also for their potential use in medical diagnostics, particularly as detectors for the ToF-PET system, whose operation requires ultra-fast scintillation to achieve high spatial precision in the detection of neoplasms. |
