Metal halide perovskites (MHPs) have attracted the attention of researchers particularly in the photo-absorption field. These materials rival traditional semiconductors with their cost-effective ease of synthesis, tunable bandgaps, and excellent photophysical properties. Single-junction MHP solar cells have rivaled current silicon-based photovoltaic devices, boasting a 25.2% light absorption conversion. Recently, MHPs have proven to be effective in x-ray detection. In this paper an investigation of three titanium-based MHPs was conducted. The goal of this research was to characterize the MHPs and determine if they are feasible materials to incorporate in x-ray detectors. After completing the research, two MHP species, FA2TiI6 and MA3TiCl7, were able to be synthesized and characterized. Their crystal systems were determined to be tetragonal with a P4/mmm space group. However, due to equipment limitations, their feasibility in x-ray detectors could not be determined.
