Synthesis

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

4 Dy + P4 → 4 DyP

Physical properties

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]

Uses

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