Halide Double Perovskites for X-ray Imaging
Since the discovery of X-rays, the development of efficient and large area detectors has been a topic of growing interest. Future advances in X-ray detector development possibly will be enabled through Metal Halide Perovskites (MHP). This recent class of semiconductors has already proven its potential in the field of opto-electronics, were metal halide perovskites have evolved as the most cost-efficient materials for future solar energy applications and emissive material for light emitting diodes. Many papers have already reported how the astonishing physicochemical properties of this material, such as efficient absorption and emission in the visible range, favorable electron-hole dynamics and ease of processing, are promising for next generation of photodetectors, including scintillators. In this PhD project I aim at unraveling the processes and pathways which determine MHP properties using ultrafast spectroscopy. These results will then be used to engineer MHP based X-ray detectors with sensitivity surpassing the one of the golden standard in the field, amorphous selenium.
