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

Heating powdered lutetium and red phosphorus in an inert atmosphere or vacuum:

{\ce {4Lu + P4 -> 4LuP}}

It can also be formed in the reaction of lutetium and phosphine.

Physical properties

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

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.
