In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, the disclosure, in one aspect, relates to compound Bi-poor perovskite crystals, methods for making the same, and ionizing and other electromagnetic radiation detectors constructed using the Bi-poor perovskite crystals. The Bi-poor perovskite crystals can be synthesized using melt-based growth methods and solution-based growth methods and contain no toxic heavy metals such as lead, cadmium, thallium, or mercury. Devices fabricated from the crystals maintain acceptable levels of performance over time. In some aspects, post-growth annealing can be used to improve the properties, including, but not limited to, room temperature resistivity and response to radiation.
