Samarium phosphide is an inorganic compound of samarium and phosphorus with the chemical formula SmP.[1][2][3]

Synthesis[]

Heating samarium and phosphorus:

Sm + P → SmP

Physical properties[]

Samarium phosphide forms crystals of a cubic system, space group Fm3m, cell size a = 0.5760 nm, Z = 4, with a structure similar to sodium chloride NaCl.[4]

The compound exists in the temperature range of 1315–2020 °C and has a homogeneity region described by the SmP1÷0.982.[5]

Chemical properties[]

Samarium phosphide readily dissolves in nitric acid.[6]

Uses[]

The compound is a semiconductor used in high power, high frequency applications and in laser diodes.[1]
