Strontium silicate (SrSiO3) is an inorganic ceramic compound belonging to the silicate family, typically studied as a wide-bandgap semiconductor material. It is primarily investigated in research contexts for optoelectronic and photonic applications, particularly as a phosphor host material and in thin-film device structures where its optical and dielectric properties are leveraged. The material is notable for its potential in scintillators, luminescent displays, and integrated photonic devices, though it remains less commercially established than conventional semiconductors and competing silicate ceramics.
