Dysprosium(III) iodide is a binary
inorganic compound of
dysprosium and
iodine with the chemical formula DyI
3.
[1]
Dysprosium(III) iodide can be obtained by reacting dysprosium with iodine.
Dysprosium(III) iodide can be obtained using the effect of mercury diiodide on dysprosium filings:
Dysprosium(III) iodide is a hygroscopic yellow-green flaky solid [2] that is soluble in water. [3] [4] The compound has a trigonal crystal structure of the bismuth(III) iodide type with the space group R3.
Dysprosium(III) iodide is used in gas discharge lamps to generate white light. [5]
