Abstract

This invention provides phosphor-doped fluoroperovskite compounds that are capable of storing at least part of the energy of incident ionizing radiation and releasing at least part of the stored energy upon optical stimulation or heating. Also provided are dosimeters and radiation storage devices comprising the compounds, methods of preparing the compounds, and methods of using the compounds to determine a dose of ionizing radiation or to record and reproduce an ionizing radiation image.
