ErSeI is a ternary ceramic compound composed of erbium, selenium, and iodine, representing a layered halide perovskite material under active research. This material falls within the family of rare-earth halides and is primarily investigated for optoelectronic and photonic applications rather than structural engineering roles. ErSeI and related compounds are of interest to researchers exploring next-generation semiconductors, particularly for applications requiring tunable bandgaps, radiation detection, or novel light-emitting devices, though it remains largely in the experimental/laboratory phase rather than established industrial production.
