Dysprosium phosphide is an inorganic compound of dysprosium and phosphorus with the chemical formula DyP.^[1]^[2]^[3]

Synthesis

The compound can be obtained by the reaction of phosphorus and dysprosium at high temperature.

4 Dy P₄ → 4 DyP

DyP has a NaCl structure (a=5.653 Å),^[4] where dysprosium is 3 valence. Its band gap is 1.15 eV, and the Hall mobility (μH) is 8.5 cm³/V·s.^[5]

DyP forms crystals of a cubic system, space group Fm3m.^[6]

The compound is a semiconductor used in high power, high frequency applications and in laser diodes.^[1]^[7]
