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

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
