Samarium(III) phosphide is aninorganic compound ofsamarium andphosphorus with the chemical formulaSmP.[1][2][3]
Samarium(III) phosphide can be obtained by heating samarium and phosphorus:
Samarium(III) phosphide forms crystals of acubic system,space groupFm3m, cell size a = 0.5760 nm, Z = 4, with a structure similar tosodium 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]
Samarium(III) phosphide readily dissolves innitric acid.[6]
Samarium(III) phosphide compound is asemiconductor used in high power, high frequency applications and inlaser diodes.[1]
