· JVASP-42667· SrCaI4

SrCaI4 is an iodide-based ceramic compound containing strontium, calcium, and iodine, representing a mixed-metal halide material family. This compound is primarily of research interest for optoelectronic and scintillation applications, where halide ceramics show promise as radiation detectors, X-ray phosphors, and potential alternatives to traditional scintillating crystals. As an emerging material rather than an established industrial product, SrCaI4 belongs to the family of inorganic halide perovskites and related structures being investigated for high-energy photon detection and imaging systems where superior stopping power or wavelength-tuned luminescence could offer advantages over conventional ceramic scintillators.
