Lutetium phosphide is an inorganic compound of lutetium and phosphorus with the chemical formula LuP.[3][4] The compound forms dark crystals, does not dissolve in water.
Synthesis
[edit]Heating powdered lutetium and red phosphorus in an inert atmosphere or vacuum:
It can also be formed in the reaction of lutetium and phosphine.
Physical properties
[edit]Lutetium phosphide forms dark cubic crystals, space group Fm3m, cell parameters a = 0.5533 nm, Z = 4.[5]
Stable in air, does not dissolve in water and reacts actively with nitric acid.
Uses
[edit]The compound is a semiconductor used in high power, high-frequency applications, and in laser diodes.[6]
Also used in gamma radiation detectors due to its ability to absorb radiation.
