Europium phosphide is an inorganic compound of europium and phosphorus with the chemical formula EuP.[2][3][4] Other phosphides are also known.[5]

Synthesis[]

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

Eu + P → EuP

Passing phosphine through a solution of europium in liquid ammonia:[6]

Eu + 2PH3 → Eu(PH2)2 + H2

with the subsequent decomposition of the when heated:

2Eu(PH2)2 → 2EuP + 2PH3 + H2

Physical properties[]

Europium(III) phosphide forms dark crystals of a cubic system, space group Fm3m, stable in air, and does not dissolve in water.

Chemical properties[]

Europium(III) phosphide actively reacts with nitric acid.[citation needed]

Uses[]

The compound is a semiconductor used in high power, high frequency applications and in laser diodes.[2]
