Dysprosium(III) iodide is a binary inorganic compound of dysprosium and iodine with the chemical formula DyI3.[1]
Synthesis
Dysprosium(III) iodide can be obtained by reacting dysprosium with iodine.
- 2Dy + 3I → 2DyI
3
- 2Dy + 3I → 2DyI
Dysprosium(III) iodide can be obtained using the effect of mercury diiodide on dysprosium filings:
- 2Dy + 3HgI
2 → 2DyI
3 + 3Hg
- 2Dy + 3HgI
Physical properties
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.
Uses
Dysprosium(III) iodide is used in gas discharge lamps to generate white light.[5]
