Lanthanum(III) oxyfluoride is an inorganic compound of lanthanum, fluorine, and oxygen with the chemical formula LaOF.[1][2]
Synthesis
[edit]Several methods of synthesizing LaOF are known:
- 2LaF3 + H2O → LaOF + 2HF
- Decomposition of lanthanum fluoride semihydrate when heated in vacuum:
- 2LaF3 · 0.5H2O → LaOF + LaF3 + 2HF
- Reacting lanthanum oxide with lanthanum fluoride in vacuum:
- La2O3 + LaF3 → 3LaOF
Physical properties
[edit]The compound forms colorless crystals.
Uses
[edit]The compound is used to produce thin films.[3][4]
