Samarium(III) phosphide is an inorganic compound of samarium and phosphorus with the chemical formula SmP.[1][2][3]
Synthesis
[edit | edit source]Samarium(III) phosphide can be obtained by heating samarium and phosphorus:
- 4 Sm + P4 → 4 SmP
Physical properties
[edit | edit source]Samarium(III) 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
[edit | edit source]Samarium(III) phosphide readily dissolves in nitric acid.[6]
Uses
[edit | edit source]Samarium(III) phosphide compound is a semiconductor used in high power, high frequency applications and in laser diodes.[1]
