Strontium iodide is an inorganic compound with the chemical formula SrI2.
It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide.
[6] In recent years, europium-doped strontium iodide (SrI2:Eu2+) has emerged as a promising scintillation material for gamma-ray spectroscopy with extremely high light yield and proportional response, exceeding that of the widely used high performance commercial scintillator LaBr3:Ce3+.
Large diameter SrI2 crystals can be grown reliably using vertical Bridgman technique [7] and are being commercialized by several companies.
At high temperatures (in the presence of air) strontium iodide completely decomposes to form strontium oxide and free iodine.
