LUTETIUM(III) IODIDE Usage And Synthesis

Uses

Lutetium iodide is used to prepare scintillation crystals. Cerium-doped lutetium iodide crystals (LuI3:Ce3+) are high-performance scintillation materials.

Application

Lutetium iodide crystals doped with rare-earth ions are materials with excellent scintillation properties. Because lutetium ions have comparable ionic radii and the same valence states as rare-earth ions, they can be doped with a large amount of various rare-earth ions. For example, cerium ion-doped lutetium iodide crystals exhibit high light output, fast decay, good energy resolution, time resolution, and linear response, and have higher luminous efficiency than rare-earth ion-doped fluoride and oxide crystals, significantly improving the efficiency of scintillation detectors. Europium ion-doped and terbium ion-doped lutetium iodide crystals also have excellent scintillation properties and can be used in security inspection, scintillation fluorescent screens, and other fields.

reaction suitability

reagent type: catalyst
core: lutetium

Synthesis

Lutetium iodide can be obtained from lutetium metal and mercuric iodide by reacting with heat:
· 2 Lu + 3 HgI2 → 2 LuI3 + 3 Hg
· The monomeric mercury produced in the reaction can be removed by distillation.
· The lutetium iodide hydrate crystallized from the solution can be heated with ammonium iodide to obtain the anhydrous material.
