Synthesis

edit

Gadolinium phosphide can be obtained by reacting gadolinium and phosphorus at high temperature, and single crystals can be obtained by mineralization.[3]

4 Gd + P4 → 4 GdP

Physical properties

edit

GdP has a NaCl-structure and transforms to a CsCl-structure at 40 GPa.[4]

GdP forms crystals of a cubic system, space group Fm3m.[5][6]

Gadolinium phosphide is antiferromagnetic.[citation needed]

Uses

edit

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