Perovskite scintillation combines excellent detection efficiency for gamma rays with high scintillation light yields and very large Stoke’s shifts of >300nm. Unlike traditional inorganic scintillators, perovskite scintillators are solution-processable at relatively low temperatures and their radioluminescence can be easily tuneable across the visible spectrum by varying the material stoichiometry.
The main objectives of the research will be as follows:
- To develop new growth methods for high light yield perovskite scintillators
- To study morphology and crystalline quality of perovskite crystals using Surrey’s new single crystal X-ray diffractometer
- To study the optical performance of the perovskite scintillators, including their photoluminescence spectroscopy and decay times
- To study the radiation response of perovskite scintillators to X-rays and gamma rays using radioisotopes and X-ray generators.
The student will be registered on the Physics PhD program; however, the nature of this research project is highly multi-disciplinary. The project will benefit from the excellent material characterisation facilities both in Chemistry and Materials Science, for example using Photoluminescence, Raman, Dynamic Light Scattering, SEM/TEM and XRD. In Physics all the requirement equipment for radiation-based characterisation of the materials is available, including X-ray luminescence and radioisotope gamma irradiation.
